They have collected a sample of 25 from each of the two classes.  The following is the summary data from each sample:                                                                         2018               2017             Sample Size                                         25                     25             Sample Mean ACT Score                    26                    25             Sample Standard Deviation            1.414                  2.06 You used JMP to solve this problem, and you got the following results:   If you are interested in testing whether or not the average ACT of college freshmen in 2018 is significantly different than that of the college freshmen in 2017, which of the following is true if α is 0.10?

This question has two related but independent parts (put the question number with its matching answer): 1) Write the header for a class called Sparkler that is: (a) a child of Firework (b) Comparable.  Make sure that the header uses the Comparable interface in its generic form so that only Sparklers can be compared with one another. 2) Write a compareTo method for Sparkler that uses the length to determine order. A Sparkler is greater than another if its length value is greater.  In your response, remember that the Sparkler implements the Comparable interface in its generic form.
