V. Given the problem below, perform the steps in hypothesis testing. A. The lifetime of a sample of 100 fluorescent bulbs produced by a company is computed to be 1570 hours. If u is the lifetime of all the bulbs produced by the company, test the hypothesis that the mean lifetime of all the fluorescent bulbs produced by the company is 1600 hours with the standard deviatic 120 hours, using the level of significance of 0.05. Step 1: State the null (Ho) and alternative (H) hypothesis. Step 2: Determine the statistical technique and level of significance. Step 3: Establish the Critical region/ decision rule. Step 4: Compute for the test statistic. SE == 8-4 Z = SE Step 5: State the decision.

solve problem V. letter A
ul Using Table- B, find the critical value(s) for each situation. Find the critical t- value for a =0.05 with d. f.= 21 for a right-tailed t- test. 2 Find the critical t- value for a = 0.05 with d. f. = 28 for a left-tailed t- test. 3. Find the critical t- value for a = 0.05 with d. f. = 18 for a two-tailed t- test. IV. Find the Z- value given the following. An engineer claims that the average weights of their products is 750 grams with population standarc deviation of 4.76. He wanted to test if this is true for 50 samples and then found out that the average weights of these samples are 812 grams. Step 1. Identify the given quantities. Step 2. Compute for the standard error of the mean. Step 3. Compute for the Z- value. V. Given the problem below, perform the steps in hypothesis testing. A.
