Samuel Morse determined that the percentage of a’s in the English language in the 1800s was 8%. A random sample of 1000 letters from a current newspaper contained 803 t’s. We want to test if the proportion of a’s in this modern newspaper is different from 0.08 using the 0.05 level of significance. (1) State the null (H0) and alternative (Ha) hypothesis using symbols. (3 pts) (2) Calculate the test statistic. Show your work. (4 pts) (3) Find the p-value using the Normal distribution table shown below for this hypothesis test. Show your work. (3 pts) (4) Determine whether we should reject or not to reject the hypothesis (state the reason to support your answer). Then state the conclusion of the hypothesis test in the context of the question. (5 pts) Assume that all required conditions are met.

The next fоur questiоns will be the pаrts оf the sаme full question on the non-constаnt dividend discount model. Non-constant dividend growth: RGV Cooling Company paid $3.30 per share in common stock dividends last year. The company's policy is to allow its dividend to grow at 9 percent for 3 years and then the rate of growth changes to 4 percent per year from year four and on. The required rate of return is 10 percent. What is its expected dividend three years from today (D3)?
