## [answered] A class of 50 students has just taken their midterm statist

A class of 50 students has just taken their midterm statistics exam.? A cursory examination of the results suggests that there is a difference between the scores of female students versus those of males.?

There are 25 females in the class.? Overall, females averaged a score of 80 on the midterm, with a standard deviation of 10 points.

There are 25 males in the class.? Overall, males averaged a score of 75 on the midterm, with a standard deviation of 12 points.

Is there a statistically significant difference between the two groups?? (Use a two-tailed test and a 95 confidence level.)

For this problem:

????????? a.)? state your assumptions (assume that the variances are not equal)

????????? c.)? compute the test statistic (use the formula in the slides)

d.)? calculate the critical value (remember to compute the appropriate degrees of freedom)?
