1. The ages of a group of tourists visiting the Library of Congress are as follows:
36, 38, 33, 44, 37, 37, 38, 34, 34, 36, 34, 40, 42, 41, 35, 48, 31, 33, 46, 47, 33, 36, 37, 37, 34, 39, 35, 37, 36, 39, 39, 39, 39, 39, 39, 39, 39, 39, 39, 39, 39, 39, 39, 39, 39, 39, 39, 39, 39, 39, 39, 39, 39, 39, 39, 39, 39,
a) Create a histogram of the ages with a 5-year class width.
b) Calculate the dataset’s mean.
b) Determine the dataset’s median.
2. True or false based on the following dataset: 13, 13, 15, 15, 16, 16, 16, 17, 18, 22.
a) The dataset above has a maximum value of 22. If the analyst makes a mistake and records it as 2.2, the mean and median of the dataset will be affected. Calculations should be displayed.
b) If a dataset’s variance is 0, then all observations must be zero as well.
c) The dataset’s standard deviation cannot be negative.
d) A dataset’s variance is always positive.
e) The graphs below show a negative correlation:
3. Three of thirteen smartphones in a shipment have damaged screens. What is the chance that the first 10 sold have an undamaged screen if they are sold in a random order?
4. There are a variety of outcomes that can occur when you toss a fair six-faced die twice:
a) Determine the sample space’s number of possible outcomes. Give an explanation for your response.
b) Determine the chances of getting a number larger than 5 on the first toss. Demonstrate your work and express your solution in the simplest fraction form possible.
c) Determine the likelihood that the total of the two throws is at least 7. Demonstrate your work and express your solution in the simplest fraction form possible.
d) Given that you acquire a number greater than 2 in the first toss, calculate the chance that the sum of the two tosses is at least 7. Demonstrate your work and express your solution in the simplest fraction form possible.
e) If event A is “getting a number bigger than four in the first throw” and event B is “the sum of two tosses is at least eight,” then Are events A and B self-contained? Justify your response.
5. SAT Math scores are regularly distributed with a population standard deviation of 200 for all seniors in a high school. Determine: If 100 seniors from the school are chosen at random and their SAT Math scores have a sample mean of 650,
1. What distribution will you use to calculate the crucial value for a confidence interval estimate of the mean SAT Math score for High School seniors? Why?
2. Create a 95 percent confidence interval estimate of the mean Math score for High School seniors. Demonstrate your effort and round your answer to the nearest two decimal places.
6. You have eight blue and eight green clothes in your closet. On Monday, you choose a shirt at random, and on Tuesday, you choose a different shirt. On Monday, you wear a blue shirt and on Tuesday, you wear a green shirt. Determine if the scenario contains an independent or dependent event. Calculate the probability.
7. You’re changing the four-digit lock’s combination. You only care about the number 1234, not the order in which it appears. Determine the number of options.
Is a 90% confidence interval estimate of the mean SAT Math score wider than the 95% confidence interval estimate you derived from part 2 of Problem 5)? Why? It is important to note that the 90 percent confidence interval does not have to be constructed.
9. Assume that the population is distributed regularly. The following hypothesis test is performed using a sample size of 225, a sample mean of 750, and a standard deviation of 30.
H0: = 745 H0: = 745 H0: = 745 H0: = 7
745Haaaaaaaaaaaaaaaaaaaa
(a) Is this a proportional, mean, or standard deviation test? For the critical value, what distribution should you use?
(b) What is the significance of the test statistic? (Exhibit your work and round to three decimal places.)
(c) What is the significance of the p-value? (Show your work and round your answer to the nearest two decimal places.) You must specify the processes if you employ technology to calculate the P-value).
A chemical test was given to 500 students. You took a random sample of 100 students to calculate the average and standard deviation. In calculating the standard deviation, how many degrees of freedom were there? (Explain why you deserve full credit.)
(a) 500; (b) 499; (c) 100; (d) 99; (e) 100; (f) 99; (g) 99; (h) 99;
