Suppose we have the following hypotheses: Ho:p=.64 H1:p>.64 What would it mean to make a Type Il error? O a. We conclude that p = .64 when it actually isn't. O b. We conclude that p = .64 and we are correct. O c. We conclude that p > .64 when it's actually smaller. O d. We conclude that p > .64 and we are correct.

represents the summary statistics for 44 blue catfish caught at this reservoir, and a 0.05 significance level to test the claim that the mean weight of the fish in the John H. Kerr Reservoir is greater than 40 pounds. n = 44; = 40.76 pounds; s = 5.12 pounds a) kdentify the null and alternative hypotheses? Ho: =V 40 H.:p>v40 b) What type of hypothesis test should you conduct (left-, right-, or two-tailed)? O left-tailed O right-tailed O two-tailed c) Identify the appropriate significance level. 0.05 d) Calculate your test statistic. (Round your final answer to two decimal places.) e) Calculate your p-value. (Round your final answer to four decimal places.) f) Do you reject the null hypothesis? O We reject the null hypothesis, since the p-value is less than the significance level. O We reject the null hypothesis, since the p-value is not less than the significance level.

A medical journal published new medical research about diastolic blood pressure. Let the mean diastolic blood pressure reading be u mmHg. If a doctor wants to know if the new medical research discussed in the journal results in diastolic blood pressure readings that are, on average, less than 75 mmHg, what are the null and alternative hypotheses? Select the correct answer below: Ho: µ = 75; Ha:H 75 %3D O Ho: µ = 75; Ha: µ + 75
A baseball team claims that the mean length of its games is 2.4 hours. State H0 and Ha in words and in symbols. Then determine whether the hypothesis test for this claim is left-tailed, right-tailed, or two-tailed. Explain your reasoning. State the null hypothesis in words and in symbols. Choose the correct answer below. A. The null hypothesis expressed in words is, "the mean length of a baseball team's games is at most 2.4 hours." The null hypothesis is expressed symbolically as, "H0: μ≤2.4." B. The null hypothesis expressed in words is, "the mean length of a baseball team's games is more than 2.4 hours." The null hypothesis is expressed symbolically as, "H0: μ≠2.4." C. The null hypothesis expressed in words is, "the mean length of a baseball team's games is at least 2.4 hours."

The commercial for the new Meat Man Barbecue claims that it takes 14 minutes for assembly. A consumer advocate thinks that the assembly time is lower than 14 minutes. The advocate surveyed 12 randomly selected people who purchased the Meat Man Barbecue and found that their average time was 13.5 minutes. The standard deviation for this survey group was 2.1 minutes. What can be concluded at the the a = 0.01 level of significance level of significance? You may assume the data are normally distributed.
