Late assignments will receive a grade of unless prior arrangements are made with me. This assignment is worth 26 points. 1. A survey conducted in a college intro stats class asked students about the number of credit hours they were taking that semester. The number of credit hours for a random sample of 16 students is given in the table. Round your answers to 1 decimal place. (2 points each) 10 10 12 14 15 15 15 15 17 17 19 20 20 20 20 22 a. Draw a histogram of these data by hand. Be sure to include your scale and labels. b. Describe the shape and modality of the histogram. c. Find the mean, median and standard deviation for the number of credit hours. 2. Suppose that the student taking 22 credit hours in the data set in the previous question was actually taking 28 credit hours instead of 22 (so we would replace the 22 in the data set with 28). Indicate whether changing the number of credit hours for that student would make each of the following summary statistics increase, decrease, or stay about the same
