The mean number of English courses taken in a two-year time
period by male and female college students is believed to be about
the same. An experiment is conducted and data are collected from 29
males and 16 females. The males took an average of two English
courses with a standard deviation of 0.8. The females took an
average of three English courses with a standard deviation of 1.1.
Are the means statistically the same? (Use α = 0.05)
NOTE: If you are using a Student’s t-distribution for
the problem, including for paired data, you may assume that the
underlying population is normally distributed. (In general, you
must first prove that assumption, though.)

Round your answer to two decimal places.) O Part (e) What is the test statistic? (If using the z distribution round your answer to two decimal places, and if using the t distribution round your answer to three decimal places.) O Part (1) What is the p-value? (Round your answer to four decimal places.)
