Question 3 (1 point)

(Continue with previous questions)The Computer Anxiety Rating Scale (CARS) measures an individual's level of computer anxiety. Researchers at Miami University administered CARS to 100 male students and 72 female students. Assume that the two samples are independent simple random samples selected from normally distributed populations, and do NOT assume that the population standard deviations are equal. Use a 0.01 significance leve, and test the claim that the mean anxiety for male is equal to the mean anxiety for female. The data are given below:

Male: n=100, sample mean=40.3, sample standard deviation=13.5

Female: n=72, sample mean=36.8, sample standard deviation=9.4

Assume that population 1 are males and population 2 are females. Answer questions 1-3:

3. State the correct conclusion for the test.

Question 3 options:

a)	Fail to reject the null hypothesis. There is not sufficient evidence to support the claim that the mean anxiety for male is the same as the mean anxiety for female.

b)	Reject the null hypothesis. There is sufficient evidence to warrant rejection of the claim that the mean anxiety for male is the same as the mean anxiety for female.

c)	Fail to reject the null hypothesis. There is not sufficient evidence to warrant rejection of the claim that the mean anxiety for male is the same as the mean anxiety for female.

d)	Reject the null hypothesis. There is sufficient evidence to support the claim that the mean anxiety for male is the same as the mean anxiety for female.
