In the Math 110 Estrada FA22 older load the data set StatCrunchUFA23. This is a random sample of 500 students. A counselor is focused on comparing the number of units between freshmen and seniors. The counselor believes that the average number of units for freshmen (Class=1) is more than that of seniors (Class=4). Determine if this data set provides statistically significant evidence to support the claim that the mean number of units is greater for freshmen than that of seniors at a 5% level of significance. Step 1: Stating the hypotheses 1 = 2 = H0 : 1-2=0, which is the same as H0 : 1=2 Ha : 1-2 0, which is the same as Ha : 1 2 Step 2: Collect Data For group 1: Determine mean, standard deviation and sample size For group 2: Determine mean, standard deviation and sample size Step 3: Assess the evidence Use Statcrunch to compute a test statistic and a P-value Step 4: State a conclusion State a conclusion in the context of the
