Determine whether the alternate hypothesis is left-tailed, right-tailed, or two-tailed. Ho : H= 3 H1 : u > 3 The alternate hypothesis is (Choose one) XBig fish: A sample of 150 flounder of a certain species have sample mean weight 47.5 grams. Scientists want to perform a hypothesis test to determine how strong the evidence is that the mean weight is greater than 46 grams. State the appropriate null and alternate hypotheses. The null hypothesis is Ho : H (Choose one) The alternate hypothesis is H, : H (Choose one)A test is made of Ho : u= 17 versus H1 : u # 17. A sample of size n= 50 is drawn, and x = 20. The population standard deviation is o = 8. (a) Compute the value of the test statistic z. (b) Is Ho rejected at the a = 0.10 level? (c) Is Ho rejected at the a = 0.05 level? Part 1 of 3 (a) Compute the value of the test statistic. Round the answer to at least two decimal places. Z : X Part 2 of 3 Choose the correct type of hypothesis test. Then find the critical values for a - 0.10 and a = 0.05. Round your answers to three decimal places, if necessary. H 1 Critical Values for a = 0.10 Critical Values for a = 0.05 O Left-tailed Right-tailed O Two-tailed and and Submit AssignrPart: 2 / 3 Part 3 of 3 Determine whether to reject Ho . (b) Since the test statistic, z = 2.65, (Choose one) in the critical region, we (Choose one) V Ho at the a = 0.10 level. (c) Since the test statistic, z = 2.65, (Choose one) in the critical region, we (Choose one) V Ho at the a = 0.05 level
