The class that graduated from a college four years ago took an average of 2.3 science courses. Since then a new curriculum requirement has been introduced. The registrar is interested in the effect this requirement has had on the enrollment in science courses. A random sample of the transcripts of 25 seniors found that the mean number of science courses taken was 2.8 with a standard deviation of 1.01 . Do these results suggest that the mean number of science courses taken has changed significantly since the new requirement was introduced? Test at a = 0.05. (a). The null and alternative hypotheses are Ho: = 2.3 Ha:ã + 2.3 O Ho: u = 2.8 Ha:µ < 2.8 Ho: µ = 2.3 Ha:H + 2.3 Ho:ã = 2.8 Ha:ã + 2.8
