The average national salary is 45,000 (in this example, 45 represents 45,000). I take a sample of 14 individuals in San Angelo and measure their average salary and obtain the following data: Individual 1 2 3 4 5 6 7 8 9 10 11 12 13 14 Salary 45 56 60 65 60 63 54 51 27 29 34 35 35 37 Conduct a test (at an alpha of .05) to answer whether or not San Angelonian’s salary is significantly greater than the national average.

A recent issue of the AARP Bulletin reported that the average weekly pay for a woman with a high school degree is $520 . Suppose you would like to determine if the average weekly pay for all working women is signicantly greater (at alpha = 0.05) than that for women with a high school degree. Using data on weekly pay for a sample of 50 working women, you obtain the following statistics: sample mean = $620, sample error = $150. Conduct the hypothesis test using the critical value approach and the p-value approach.Describe the conclusion of the hypothesis test and what that means in this context
A researcher wants to know if a treatment significantly changes the wellbeing of someone with depression. The average person with depression scores a 7.2 on a wellbeing scale with a SD of 1.4 points. The researcher administers the treatment to 25 clients for a month and finds their wellbeing at the end to be 7.7. Assume an alpha level of .05. Imagine we know that a treatment actually does have an effect but the researcher concludes there is no effect. 1a. What error has the researcher made? 1b. Why might a researcher make this error? 1c. What is the probability of this error? 1d. How could we decrease this probability?
QUESTION 2 To test the effect of a new medication on pulse rate, the researcher randomly selected the 60 subjects into two groups of 30. New medicine and placebo were given to Group 1 and Group 2, respectively. Below is the Minitab output. Two-Sample T-Test and CI Group Мean StDev SE Mean 1 30 65.20 7.80 1.4 2 30 70.30 8.40 1.5 Difference = mu (1) - mu (2) Estimate for difference: 95% CI for difference: T-Test of difference = 0 (vs not =): T-Value = -2.44 -5.10 (-9.29, -0.91) P-Value=0.018 DF=57 ii) Using to.025,57 = 2.003 shows that the 95% confidence interval for the difference in mean pulse rate between new medication and placebo is (-9.29, -0.91). Hence, interpret its meaning.
