In the year 2008, a real state agent earned an average of Php 40,250.00 a month. Suppose you recently selected a random sample of a 40 real state agents. You determined how much each of them earns each month. Your computations of their earnings resulted to an average of Php 40,400.00 with a standard deviation of Php 225.00 Using a= 0.01, can it be concluded that the average month earnings of a real state agent has increased? Use one population z-test/t-test. Determine a) null and alternative hypothesis b) level of significance and critical values c) value of the test statistics, decision about null hypothesis and conclusion.

Suppose that a recent article by a historian stated that the mean time spent in jail by a first–timeconvicted burglar in the 20th century was 2.5 years. A study was then done to see if the mean time has increasedin the new century. A random sample of 26 first-time convicted burglars in a recent year was picked. The meanlength of time in jail from the survey was 3 years. Suppose that it is somehow known that the population standarddeviation is 1.8 years and that the population is normally distributed.The hypotheses can then be framed as:H0 : μ = 2.5 vs. Ha : μ > 2.5(a) Which of the following figures (next page) best describes the p-value for this hypothesis testingproblem. Explain your reasoning. (numbers above red shaded area represent the corresponding probabilities). (b) Write the decision and conclusion for this hypothesis testing problem if the significance level, α,is 0.1.
According to the New York Daily News, March 5, 2014, people 65 years and older watch an average of 50.5 hours of TV per week. We will estimate the standard deviation to be 12.7 hours per week. Your town has many social programs for senior citizens which may reduce the amount of TV that older people watch. You want to find out if it is true that people 65 and older in your town watch less than 50.5 hours of TV per week. So, you sample 40 people 65 and older in your town. You find that the average time that the 40 people watch per week is 45.8 hours. Can the claim be supported to a level of significance of α = .02, test the hypothesis?
