You are tasked with determining if there is a difference in the average number of years of education of men and women in California. You take a random sample of 1,800 men and 3,200 women. The average education in your sample of men is 13 years with a sample standard deviation of 3 years. The average education in your sample of women is 14 years with a sample standard deviation of years.

a. What is your null hypothesis?

b. What is your alternative hypothesis?

c. State your conclusion regarding the difference in average education, using 5% significance.

d. What is the 95% confidence interval for the difference in average wages?

The owner of a local golf course wants to examine the difference between the average ages of males and females that play on the golf course. Specifically, he wants to test is if the average age of males is greater than the average age of females. Assuming males are considered group 1 and females are group 2, this means the hypotheses he wants to tests are as follows: Null Hypothesis: μ1 ≤ μ2, Alternative Hypothesis: μ1 > μ2. He randomly...

A sociologist studied gender differences in the average number of hours worked per day among employees at a law firm (there are 42 men and 19 women employed at this firm). She obtained the following results: men work, on average, 52 hour per week and women work, on average, 56 hour per week. The standard deviation for men is 12 hours and the standard deviation for women is 9 hours. Test the null hypothesis of no difference in the average...

Suppose you want to test the notion that individuals perceive a greater height difference between men and women than actually exists, due to stereotyping. The true population difference between the height of men and women is an average of 5 inches. You obtain a random sample of 400 individuals and record their perceptions of the mean difference in height between men and women. You find that the sample perceives the difference between men and women to average 6 inches. The...

Test the following null hypothesis at a=.05 Ho: u men = u women Ha: u men > u women You need to compute the t statistic, look up t critical value and make decision including likelihood of appropriate error. You don't have to compute the standard error of mean difference because it's given. 1b. Compute...
