Suppose average starting salary for business majors is $52236 and for communications majors it is $47047 (according to NACE for 2016). Suppose the sample sizes are 619 and 76 and that the standard deviations are $6,700 and $8,650. Is there compelling evidence that the mean salary for business majors is higher than the mean salary for communications majors? Construct a hypothesis to test. Report the critical value when α = .05, the standard error, the test statistic, and your conclusion. Note that there are 86 degrees of freedom.
