Alternative hypothesis: the graduates from a university earn more than that average.
Using the z-test:
=> Calculate the value of test statistic:
t = (mean of sample - mean of null hypothesis)/(std/sqrt(number of sample)
= (53200 - 50556)/(10200/sqrt(100))
= 2.592 > 1.645
=> Reject the null hypothesis, their graduates earn more than average
Hope this helps!
