Use the following information to answer the remaining questions. A study is done comparing the effect on the growth of plants by two different types of fertilizer. Fertilizer A is used with one group of 31 plants. The average height of the plants after 6 weeks was 10.7 inches with a standard deviation of 3.2 inches. The other group of 35 plants was fertilized with Fertilizer B. These plants had an average height of 8.7 inches with a standard deviation of 2.1 inches. Assume the plant heights for both populations are normally distributed. For this problem, assume the population variances are equal. If needed, use a level of signicance of or = 0.05. Answer the following for the hypotheses that are given. Ho: O'A=4 H1: O'A
