Central question: Which major, business or engineering, will give the better ROI?

Using the ROI data set:According to the textbook, what are the characteristics of a binomial experiment? Explain how the following scenario fits EACH of the requirements for a binomial experiment. Scenario: We randomly select 7 colleges from the business major and then record whether they are of ‘School Type’ ‘Private’ or not.In a perfect normal distribution, if the mean is 23, what is the median? What is the mode?For each of the 2 majors determine if the ‘Annual % ROI’ appears to be normally distributed. Use a histogram and the measures of central tendency (mean and median) to justify your results. #2 above is a big hint for how to justify whether the Annual ROI is normally distributed. In a highlighted box, explain how having or not having a normal distribution for each of the majors may affect your ability to compare the data of the two majors. In a normal distribution, what percent of values falls 1 standard deviation from the mean? Two standard deviations from the mean? Three standard deviations from the mean?
