- Independent samples t-test (continued): A researcher is interested in determining if men are more likely than women to know how to cook. She takes a random survey testing respondents’ knowledge of food preparation methods and generates the following data:
Women: number of correct responses mean of group 1= 15; S1= 4.4; N1= 130
Men: number of correct responses mean of group 2 = 10; S2= 3.1; N2= 110
- Which of the following best approximates the calculated t?
Select one:
a. 9.7
b. 5.2
c. .97
d. .52

For the following test, assume that the two samples are independent simple random samples selected from normally distributed populations and that the population standard deviations are equal (1 = 02) so that the standard error of the difference between means is obtained by pooling the sample variances. A researcher was interested in comparing the amount of time spent studying baboons by women and men from a group of anthropologists. Independent simple random samples of 32 women and 30 men were...
