Claim: UCF is advertising their bachelor in Economics with the statistic that the starting salary of a graduate with a bachelor in economics is $ 48,500 according to Payscale (2013-13).

Null hypothesis:

Alternate hypothesis :

n = 50

Since n is more than 30 .

So we will use Z test

x=43350

Standard deviation = 15000

Refer the z table

p value = 0.00776

p value <

So, We are failed to accept null hypothesis

Hence The claim is rejected
