university administration claims that its students graduate on average in 4.5 years. A newspaper believes the average time to graduation is higher and polls 100 recent graduates at random. The average time to graduation for the sample is 4.6 years, with a sample standard deviation of 0.5 years. The newspaper wants to publish an article disputing the administrations claim, but it only wants to do so if it has strong evidence against the claim. Use this data to perform an appropriate hypothesis test for the realtor with a = 0.10. Calculate a p-value for an appropriate test of hypotheses and describe the level of evidence you find in words. Be sure to state the null and alternative hypotheses clearly.
