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 0.9. The females took an average of three English courses with a standard deviation of 1.1. Are the means statistically the same? (Use  ? = 0.05)   State the distribution to use for the test. (Enter your answer in the form z or tdf where df is the degrees of freedom. Round your answer to two decimal places.)   What is the test statistic?    What is the p-value?    Sketch a picture of this situation. Label and scale the horizontal axis and shade the region(s) corresponding to the p-value.
