For a particular sample of 80 scores on a psychology exam, the following results were obtained.First quartile = 65 Third quartile = 98 Standard deviation = 8 Range = 56Mean = 83 Median = 81 Mode = 59 Midrange = 64
Answer each of the following:
I. What score was earned by more students than any other score? Why?II. What was the highest score earned on the exam?III. What was the lowest score earned on the exam?IV. According to Chebyshev's Theorem, how many students scored between 67 and 99?V. Assume that the distribution is normal. Based on the Empirical Rule, how many students scored between 67 and 99?
Assuming that a hypothesis test of the claim has been conducted and that the conclusion is failure to reject the null hypothesis, state the conclusion in nontechnical terms.
Find the standard error of the difference in sample means,
Repeat this process 10 times or you can draw 10 samples simultaneously using StatTools. Make a histogram of the 10 values of sample means. You are constructing the sampling distribution of sample means. What is the center of your histogram?

In as sample of 855 bartenders, 48% report hearing complaints from patrons about their jobs. If the maximum error of estimate for the proportion of bartenders hearing job complaints is 4.4 percentage points, what is the degree of confidence used?
If the process mean and standard deviation remain constant, what proportion of the output from this process will be defective?
Using the original data, estimate the population standard deviation with 90% probability.
nterpret the meaning of the y-intercept, b(0), and the slope, b(1), in this problem. Use the prediction line developed in (a) to predict the GPA for a student a GMAT score of 600
Formulating null and alternative hypothesis to test the claim averaging about $5000.
Suppose you want to sell your house and you have decided to accept the first offer exceeding M dollars, say. Assume that the offers are i.i.d. with common distribution F. Find the expected number of offers received before selling the house.
There is an advantage in stating the hypothesis both in the null and in the alternative; it adds clarity to our thinking of what we are testing. Explain.
