Answer: what is the question

Step-by-step explanation:

The public relations officer for a particular city claims the average monthly cost for childcare outside the home for a single child is $600. A potential resident is interested in whether the claim is correct. She obtains a random sample of 14 records and computes the average monthly cost of this type of childcare to be $589 with a standard deviation of $40. Perform the appropriate test of hypothesis for the potential resident using . Approximate the p-value for the test in (a).

Answers

Answer:

Since the calculated value of z= -1.0198 does not lie in the critical region z = ± 1.96 the null hypothesis is accepted and it is concluded that the average monthly cost for childcare outside the home for a single child is $600.

P- value ≈ 0.307823 which supports the null hypothesis .

Step-by-step explanation:

The null and alternate hypotheses are

H0: u = $600 the average monthly cost for childcare outside the home for a single child is $600.

against the claim

Ha: u ≠ $600 the average monthly cost for childcare outside the home for a single child is not equal to $600.

The significance level is set at 0.05

3) The critical region is z = ±1.96

4) The test statistic

Z=x- u /s/√n

z= 589-600/40/√14

z= -11/10.7681

z= -1.0198

6) Conclusion

P- value ≈ 0.307823 which supports the null hypothesis .

Answer:

No, it is not.

An irrational number is real number that cannot be expressed as a ratio of two integers. The number pi or π is a common example of an irrational number since it has an infinite number of digits after the decimal point. Many square roots are also irrational since they cannot be reduced to fractions.

7. A box contains 10 black, 12 white, and 18 red balls. One ball is drawn at

table below, find the experimental probability that the ball drawn is black.
(c) Compare the experimental probability of the black ball drawn to its
theoretical probability.
Table:
Color. Times picked
black. 15
white. 12
red. 13

Answers

Answer:

1. 10/40 = 1/4

1b. 15/40 = 3/8

1c. 10/40 = 1/4 and 15/40 = 3/8

Step-by-step explanation:

1. So since there are 40 balls (18 + 12 + 10) and 10 of those balls are black the theoretical probability would just be 10 over 40, ([tex]\frac{10}{40}[/tex]).

1b. On the table there are 15 black balls so that would be, [tex]\frac{15}{40}[/tex].

1c. The theoretical probability is 1/4 and the experimental probability is 3/8.

Answer: -3

Step-by-step explanation: well there is a pretty easy explanation for this because what you pretty much do is you put the answer around by doing 5-2 and just put a negative since the smaller number is in the front.

The answer is… 2 - 5 = -3
This is simple math so regularly since you will get a negative if it is puted as 2 - 5. So you might as well do the simple math 2 - 5, than as soon as you get your answer than just put a negative sign since it isn’t in the basic number scale, but instead on the negative number scale.

Vance invests S15,000 in an account that pays 3 1/4% simple interest for 72 months. Assuming Vance doesn't
make any other deposits or withdrawals, how much will be in his account after 72 months?

Answers

Answer:

$15487.5

Step-by-step explanation:

Using the formula for calculating the amount as;

Amount = Principal + Interest

Principal = $15,000

Get the interest

Interest = PRT/100

Interest = 15000*13/4 * 3/100 (72months = 3years)

Interest = 195000/400

Interest = $487.5

Amount = 15000 + 487.5

Amount= $15487.5

Hence he will have $15487.5 in his account after 72months

Answer:

A. 12.7

Step-by-step explanation:

If line a is parallel to line b, therefore,

(10x - 13.3) = (8x + 12.1) => alternate interior angles theorem

Solve for x

10x - 13.3 = 8x + 12.1

Collect like terms

10x - 8x = 13.3 + 12.1

2x = 25.4

Divide both sides by 2

x = 25.4/2

x = 12.7

The Company has spent $5 million in research and development over the past 12 months developing cutting-edge battery technology which will be incorporated into the electric vehicle market. INT now need to choose between the following three options for bringing the product to market. These options are: Option 1: Manufacturing the product in-house and selling directly to the market Option 2: Licensing another company to manufacture and sell the product in return for a royalty Option 3: Sell the patent rights outright to the company mentioned in option 2 Your task Your manager, INTs CFO, Mr Barry Smith, has asked you to evaluate the three different options and draft a memo to the Board of Directors providing recommendations on the alternatives, along with supporting analyses. Mr Smith has outlined the following three (3) areas you need to cover in your memo: a) Analyse base case figures for the three options and using NPV as the investment decision rule; b) Provide recommendations based on the base-case analyses; c) Provide recommendations on further analyses and discuss factors that should be considered prior to making a final decision on the three options (Note. You do NOT have to undertake any further financial analyses). Further details for the various options are as follows: Option 1: Manufacturing the product in-house and selling directly to the market Three months ago, INT paid an external consultant $1.5 million for a production plan and demand analysis. The consultant recommended producing and selling the product for five years only as technological innovation will likely render the market too competitive to be profitable enough after that time. Sales of the product are estimated as follows: In the first year, it is estimated that the product will be sold for $45,000 per unit. However, the price will drop in the following three years to $40,000 per unit and fall again to $36,000 per unit in the final year of the project, reflecting the effects of anticipated competition and improving technology Year Estimated sales volume (units) 1 5,200 2 4,600 3 4,200 4 3,800 5 3,600In the first year, it is estimated that the product will be sold for $45,000 per unit. However, the price will drop in the following three years to $40,000 per unit and fall again to $36,000 per unit in the final year of the project, reflecting the effects of anticipated competition and improving technologyin the market. Variable production costs are estimated to be $29,000 per unit for the entire life of the project. Fixed production costs (excluding depreciation) are predicted to be $3 million per year and marketing costs will be $1.6 million per year. Production will take place in factory space the company owns and currently rents to another business for $2.5 million per year. Equipment costing $87 million will have to be purchased. This equipment will be depreciated for tax purposes using the prime cost method at a rate of 10% per annum. At the end of the project, the company expects to be able to sell the equipment for $37 million. Investment in net working capital will also be required. It is estimated that accounts receivable will be 30% of sales, while inventory and accounts payable will each be 25% of variable and fixed production costs (excluding depreciation). This investment is required from the beginning of the project because credit sales, inventory stocks and purchases on trade credit will begin building up immediately. All accounts receivable will be collected, suppliers paid and inventories sold by the end of the project, thus the investment in net working capital will be returned at that point.
