Pennsylvania Seniors Favorite Subject? Exercise 1.24 describes a dataset, stored in PASeniors, for a sample of 457 Pennsylvania high school seniors who did the Census at School project. The data contain responses from the decade 2010-2019. One of the questions asks about favorite school subject. We see that 39 out of 186 students fromthe first half of the decade (2010-2014) chose "mathematics and statistics," while 69 out of 268 students in the second half of the decade (2015-2019) made this choice. (Three students did not answer this question.) Does this provide enough evidence that the proportion of students picking mathematics and statistics as a favorite subject has changed between the first and second halves of the decade? (Let Group 1 represent the first half of the decade and Group 2 represent the second half of the decade.) Your answer is correct.
