Ticket sales for the next two days are 55 tickets and 68 tickets. Which statement about the data is true?
a
The range stays the same.
b
The range increases by two.
c
The range decreases.
d
The range doubles.
Ticket sales for the next two days are 55 tickets and 68 tickets. The range doubles. The correct option is d.
What is Range?The range of a dataset is the difference between the highest and lowest values. The highest value here is 68, and the lowest value is 55. As a result, the range is 68 - 55 = 13.
The range in statistics refers to the difference between the highest and lowest values in a dataset. It is a measure of dispersion that indicates how dispersed the data is.
The range is a quick and simple way to determine how much variability exists in a dataset. It is, however, influenced by outliers or extreme values in the dataset.
The range doubles because the highest and lowest values are the same on both days.
Thus, the correct option is d.

Determine the length of the diagonals of the isosceles trapezoid below when KL= h+7 and UE= 4h-25
Answer:
KL= 17.67 unit
UE = 17.67 unit
Step-by-step explanation:
Given:
Diagonals
KL= h+7
UE = 4h-25
Find:
Length of diagonals KL and UE
Computation:
We know that in isosceles trapezoid the length of diagonals are equal
So,
KL = UE
h+7 = 4h-25
3h = 32
h = 10.67
So,
KL= h+7
KL= 10.67+7
KL= 17.67 unit
UE = 4h-25
UE = 4(10.67)-25
UE = 17.67 unit

A contract between a manufacturer and a consumer of light bulbs specifies that the mean lifetime of the bulbs must be at least 1000 hours. As part of the quality assurance program, the manufacturer will institute an inspection program for each day's production of 10,000 units. An ordinary testing procedure is difficult since 1000 hours is over 41 days! Since the lifetime of a bulb decreases as the voltage applied increases, a common procedure is to perform an accelerated lifetime test in which the bulbs are lit using 400 volts (compared to the usual 110 volts). At such a voltage, a 1000-hour bulb is expected to last only 3 hours. This is a well-known procedure, and both sides have agreed that the results from the accelerated test will be a valid indicator of lifetime of the bulb.
The manufacturer will test the hypotheses H0 : µ = 3 versus Ha: µ < 3 at the α = 0.01 significance level with a simple random sample of 100 bulbs.
a. Describe what a Type I error would be in this context.
b. Describe what a Type II error would be in this context.
c. Which error—Type I or Type II—is likely to do more damage to the manufacturer’s relationship with the consumer? Explain.
Answer:
Follows are the solution to the given points:
Step-by-step explanation:
In point a:
In this sense, describe what type of error I will be.
Type I error: to conclude that perhaps the mean bulb life would be less than three hours when it becomes (at least) 3 hours.
In point b:
Describe throughout this context what the Type II error becomes.
An error of type II: never assuming that its bulbs' mean lifetime is much less than 3 hours. three hours at least
In point c:
What error — type I and type II — would further impact the interaction between the manufacturer and the customer?
A Type II error is probably further problematic because it means that even the buyer will buy bulbs that do not last long.

American Vending supplies vended food to a large university. Because students often kick the machines out of anger and frustration, management has a constant repair problem. The machines break down in a mean of 3 hours with a standard deviation of 3 hours. One repair worker can service one machine in a mean of 2 hours with a standard deviation of 2 hours. Currently, TWO repair workers are hired. Average flow time (W) was calculated as 2.305 from the posted queueing template. --- Average down machines in the entire system (L) are ___.
Answer:
0.77
Step-by-step explanation:
From the information given:
The breakdown time (a)= 3 hours
The breakdown rate (λ) = 1/a = 1/3
Average flow time in the system (W) = 2.305 hours
For the entire system;
The average down machines L = Wλ
= 2.305 × (1/3)
= 0.77

a spinner with four equal-size sections marked M, A, T, and H is spun 100 times. The results are shown below.
What is the theoretical probability of landing on T?
What is the experimental probability of landing on a consonant?
Compare the theoretical probability to the experimental probability of landing on H.
Answer:
there's four of them so it's a movie 25 / 100 would be the probability of landing on them
The experimental probability of landing on a consonant is more than the theoretical probability of landing on T because P(T) = 1/4 is less than P(Consonant) = 79 / 100.
What is probability?The probability is given as,
P = (Favorable event) / (Total event)
A spinner with four equal-size sections marked M, A, T, and H is spun 100 times. The results are shown below.

H 25
The theoretical probability of landing on T will be given as,
P(T) = 1/4
P(T) = 25/100
The experimental probability of landing on a consonant is given as,
P(Consonant) = 79 / 100
