2. I also want to know if teenage men are bigger sports fans than teenage women. Assuming the populations are approximately normal, I surveyed 15 teenage men and found they watched 6.2 hours of sports per week with a standard deviation of 1.5 hours. I surveyed 13 teenage women and found an average of 7.5 with a standard deviation of 1.6 hours. Find a 95% confidence interval to estimate the difference of men’s to women’s means assuming the variances of the populations are the same.

Answer :

95% confidence interval for mean difference of men's to women's ;

( -2.505 , -0.095 )

Explanation :

If you want to how to find the value in T table then see;

In t table corresponding value of df = 26 & two tailed = 0.05 then value is 2.056 will be obtained

In the field of economics, there are few men who cast a bigger shadow than Milton Friedman. One of his (among many) central ideas is the Friedman Doctrine which states that corporations have no social responsibility (as long as they play by the rules) beyond profit maximization. This approach is often criticized by those that believe corporations should be good "corporate citizens".   You will research the life and career of Milton Friedman providing an overview of his life and main...

I often see many more women at the park exercising than I do men. Due to my observations, I believe that women exercise more often than men. In order to test my hypothesis, I asked 10 random men and 10 random women how many times they exercise a week. The men's answers were: 6, 2, 3, 1, 4, 3, 2, 7, 4, 2, and the women's were: 5, 4, 2, 4, 7, 6, 5, 6, 4, 3. Is there significant...

We want to know how medical care costs differ between men and women. Assume medical cost follows a normal distribution. Among the 110 men surveyed, the average medical cost is $7163 with standard deviation $6663. Among the 90 women surveyed, the average medical cost is $6224 with a standard deviation $3277. (1) Construct the 95% CI for medical care costs for men and women separately. (4 points) (2) Conduct a hypothesis testing to test whether the medical costs differ between...

A personality psychologist wanted to know if men and women differ in their sympathy and compassion expressed to others. She gave a personality test to randomly selected men and women. One component of the test measured empathy, with higher scores indicating more empathy. The data are shown in the spreadsheet. Carry out a t-test on H0: μ M = μ W (population means for Men and Women are the same) vs. Ha: μ M ≠ μ W (population means for...
