Question
(A Goodness-Of-Fit Test). Several years ago, a census of all students enrolled at
a large undergraduate university revealed that 19% of the students were seniors,
23% were juniors, 27% were sophomores, and 31% were freshmen. This year, the
student senate did a survey to see whether these percentages have remained the
same. A random sample of 200 students included 50 senior, 46 juniors, 55
sophomores, and 49 freshmen. Using a 2.5% significance level, test the null
hypothesis that 19% of the students this year are seniors, 23% are juniors, 27%
are sophomores, and 31% are freshmen.
