(trying to figure out how many hours is 464 minutes)

A manufacturing plant has two assembly lines for producing glass bottles. The manager

was concerned about whether the proportion of defective bottles differs between the two

assembly lines. She gathered two independent samples and found the following data:

n 1 =100, ^p 1 =.1,n 2 =100, ^p 2 =.13.

(a) Set up the appropriate null and alternative hypotheses.

(b) Compute the value of the test statistic.

(c) Draw a conclusion as to whether there is a difference between the two assembly lines

Therefore , the p- value is 0.008 , thus half of population is supporting.

A hypothesis is a proposed explanation for a phenomenon. The scientific method states that a theory cannot be deemed scientific unless it has been put to the test. The majority of scientific ideas are founded on historical findings that are insufficiently explained by current knowledge.

Here,

test statistics Z=

Z = [tex]\frac{p-p'}{\sqrt{p'(1-p')/n} }[/tex]

for

H0 : p= 0.5

And

Ha: p>0.5

Z =(0.585-0.5) / ((0.5)(0.5)/200)

Z=2.4

Since p =x/n=117/200=0.585

Thus

p- value= P(Z>2.4)=1-Ф(2.4)=1-0.992 =0.008

Therefore , the p- value is 0.008 , thus half of population is supporting.

The sample size should be 24.

What is the sample size?

The process of deciding how many observations or replicates to include in a statistical sample is known as sample size determination. Any empirical study with the aim of drawing conclusions about a population from a sample must take into account the sample size as a crucial component.

Here, we have

Given

Margin of error = 300

confidence level = 0.9

standard deviation = 900

Assuming the standard deviation to be of population

ME = Z(0.1/2) × σ/√n

The system of equations for the given situation are 14=b-c ; 35=b+c and the speed of boat is 24.5 miles/hr and speed of current is 10.5 miles/hr.

Given,

Distance covered by boat in upstream in 3 hours = 42 miles

Distance covered by boat in downstream in 2 hours = 70 miles.

Let

speed of boat in still water be 'b'

speed of current of stream be 'c'

we know that distance=speed x time

If the boat is moving upstream, the current (which is 'c' miles per hour) will push against it, reducing the boat's speed by 'c' miles per hour. The boat's resulting speed (as it travels upstream) is 'b-c' miles per hour. If, on the other hand, the boat is travelling downstream, the current will push it faster, increasing the boat's speed by 'c' miles per hour. The boat's downstream speed is 'b+c' miles per hour as a result.

Then the system of equations will be

distance while going upstream ,

distance=speed x time

42=(b-c)(3)

14=b-c....i

distance while going downstream,

70=(b+c)(2)

35=b+c....ii

solving eq. i and eq. ii

14=b-c

35=b+c

------------

49=2b

b=24.5

Substitute in eq. i,

14=24.5-c

c=24.5-14

There are 12 even integers are there between 200 and 700 whose digits are all different and come from the set (1, 2, 5, 7, 8, 9}.

What is number of permutation?

Take the number of possibilities for each event and multiply it by itself X times, where X is the total number of events in the sequence, to determine the number of permutations.

For instance, four-digit PINs have 10 possible combinations because each digit can range from 0 to 9.

We see that the last digit of the 3 -digit number must be even to have an even number. Therefore, the last digit must either be 2 or 8.

Case 1 - the last digit is 2. We must have the hundreds digit to be 5 and the tens digit to be any 1 of {1,7,8,9}, thus obtaining 4 numbers total.

Case 2 - the last digit is 8. We now can have 2 or 5 to be the hundreds digit, and any choice still gives us 4 choices for the tens digit. Therefore, we have 2 x 4 = 8 numbers.

Adding up our cases, we have 4 + 8 = 12 numbers.

Hence, there are 12 even integers are there between 200 and 700 whose digits are all different and come from the set (1, 2, 5, 7, 8, 9}.

A car is selected from random sample of 100 cars,

a) The events for which the selected car has 2 doors and 4 doors are mutually exclusive event ;

i.e P(A ∩ B) = 0.

b) The probability that a randomly selected car from this sample had 2 doors or 4 doors is 0.77..

Mutually exclusive event :

A and B are mutually exclusive if they cannot occur at the same time. This means that A and B have no common result and P(A and B) = 0.

We have given a Venn diagram which consists the cars have sunroof , 2 doors and 4 doors.

Firstly we need to understand the Venn diagram properly for determining the required probability values.

From Venn diagram ,

Total number of cars in sample = 100

Cars with sunroof only = 13

Number of cars with 2 doors only = 14

Number of cars with 4 doors only = 25

Number of cars with sunroof and 2 doors = 18

Number of cars with sunroof and 4 doors = 20

a) let us consider two events A and B

A : car with two doors

B : car with four doors

As we see in Venn diagram,

the number of cars with 4 doors and 2 door, n(A∩B) = 0 => P(A and B) = 0

so, by definition of mutually exclusive event

A and B are are mutually exclusive events.

b) Probability that car with 2 doors, P(A)

= favourable outcomes for A / total outcomes

= 14+18/100 = 32/100

Probability that car with 4 doors, P(B)

= favourable cases for B/ total outcomes

= 25+20/100 = 45/100

Probability that randomly selected car from this sample had 2 doors or 4 doors = P( A or B)

= P(A) + P(B) = 77/100 = 0.77

Hence, the required probability is 0.77..

The option that has the best insight of how to find the experimental probability of rolling a 3 is option A

A. To find the experimental probability of rolling a three, write a ratio of the number of times three occurs to the total number of trials. Simplify if necessary.

An experimental probability is a probability based on real  or actual experiment, such that the result depends on the accuracy of the record of the occurrences during the experiment.

The result from the experiment is presented as follows;

The probability of an event is the ratio of the number of possible outcome to the number of required outcome.

Therefore: The probability of rolling a three is the ratio of the frequency of an outcome of threes to the sum of the frequency of all the events.

The correct option from which the best details of finding an experimental  probability can be obtained is the option that states that the experimental probability of rolling a three is the ratio of the count of the number of times three occurs to the total number of trials, which is the frequency of rolling a three to the sum of all the frequencies in the experiment.

Mathematically, we get;

The probability of an event E, P(E) = [tex]\frac{Number\, of \, outcomes \, three}{Total \, number \, of \, outcomes}[/tex]

Therefore

[tex]P(3) = \dfrac{Number\, of \, times \, three\, occurs }{Total\, number \, of \, trials} = \dfrac{Freqiuency\ of \ 3s }{Sum\ of \ ther \ frequencies}[/tex]

[tex]P(3) = \dfrac{5}{4+6+5+7+3+5} =\dfrac{1}{6}[/tex]

Answer:

To find the product of 1/4 and 1/6, we need to first find a common denominator. In this case, we can use the least common multiple of 4 and 6, which is 12. We can then rewrite 1/4 and 1/6 as 6/12 and 2/12, respectively. The product of these two fractions is then 6/12 * 2/12 = (6 * 2)/(12 * 12) = 1/12. Therefore, 1/4 x 1/6 = 1/12.

Alternatively, we can simply cancel out common factors in the numerator and denominator of the two fractions before multiplying them. In this case, we can cancel out the common factor of 1 in the numerator and the common factor of 4 in the denominator to get 1/4 * 1/6 = 1/(4 * 6) = 1/24.
