3) A college wants to see if there is a significant difference in the amount of time an average full- time student studies each week compared to the national average of 17 hours. Given that a random sample of 140 students studied an average of 15.5 hours with a population standard deviation of 6.4 hours, determine if there is a significant difference between this college and the national average. Test at a 95% confidence level. (a < 0.05) Hg: μ = 17 The null and alternative hypotheses: a) Compute the test statistic (z-score): b) What is the p-value for the test statistic? c) State your conclusion in a complete sentence: HA: # 17
