Please answer the following questions? Explain how you got those answers? I need to know how to do it for my test next week. Thanks!
Which of the below-mentioned hypotheses is assumed to be true while we perform a hypothesis test?
When conducting a hypothesis test, we hope to avoid commiting a type 1 error, which is: 1. Not as bad as committing a type 2 error 2. rejecting a null hypothesis when it is true 3. rejecting the alternate hypothesis when it is true 4. accepting the null hypothesis when the alternate hypothesis is true
The P-value for a hypothesis test is shown. Use the P-value to decide whether to reject Ho when the level of significance is (a) a = 0.01, (b) a = 0.05, and (c) a = 0.10. P=0.1162 (a) Do you reject or fail to reject H, at the 0.01 level of significance? O A. Reject H, because the P-value, 0.1162, is greater than a = 0.01. O B. Reject H, because the P-value, 0.1162, is less than a= 0.01. O C. Fail to reject Ho because the P-value, 0.1162, is less than a= 0.01. O D. Fail to reject H, because the P-value, 0.1162, is greater than a = 0.01. (b) Do you reject or fail to reject H, at the 0.05 level of significance? O A. Fail to reject H, because the P-value, 0.1162, is less than a = 0.05. O B. Reject Họ because the P-value, 0.1162, is greater than a = 0.05. O C. Fail to reject Ho because the P-value, 0.1162, is greater than a = 0.05. O D. Reject H, because the P-value, 0.1162, is less than oa = 0.05. (c) Do you reject or fail to reject Ho at the 0.10 level of significance? O A. Reject H,…
I. Do the following:a. State the null and alternative hypotheses, identify which represents the claim,b. Determine when a type I or type II error occurs for a hypothesis test of the claim.c. Determine whether the hypothesis test is left-tailed, right-tailed, or two-tailed. Explain your reasoning.d. Explain how you should interpret a decision that rejects the null hypothesis.e. Explain how you should interpret a decision that fails to reject the null hypothesis.ProblemAn agricultural cooperative guarantees that the mean shelf life of a certain type of dried fruit is at least 400 days.II. Conduct a hypothesis testA research center claims that less than 50% of senior high school students in public schools in the Philippines have accessed the Internet using cellular phones. In a random sample of 100 SHS students, 39% say they have accessed the Internet using cellular phones. At = 0.01, is there enough evidence to support the researcher’s claim?

In performing a hypothesis test, one should decide whether to reject or not reject the null hypothesis before summarizing the results. True or false. Explain.
Which set of numbers would correspond to a hypothesis test with the greatest power? Cohen's d = 0.6 & n = 500 O Cohen's d = 0.6 & n = 50 O Cohen's d = 0.5 & n = 50 O Cohen's d = 0.5 & n = 500
A researchers claims 45% of couples have children. They conduct a hypothesis test and reject the null hypothesis. What type of error could have been committed here? Type 1, type 2, or power if the test?
A radio station states that 30% of the songs they play each week are from Canadian artists. A DJ working at the station claims that the actual percentage differs from what the station states. The DJ takes a random sample of 87 songs played during a given week and finds that 28 of them are from Canadian artists. Use this information to answer the questions below. a. Suppose the DJ wishes to perform a hypothesis test of his claim. Select the most appropriate null and alternative hypotheses for this hypothesis test. H0:p^≠0.3Ha:p^=0.3 H0:x―=0.3Ha:x―≠0.3 H0:μ≠0.3Ha:μ=0.3 H0:p=0.3Ha:p≠0.3 H0:μ=0.3Ha:μ≠0.3 H0:p≠0.3Ha:p=0.3 H0:p^=0.3Ha:p^≠0.3 H0:x―≠0.3Ha:x―=0.3 b. To assess his hypothesis, the DJ wants to compute a bootstrap-based confidence interval from his sample. Which of the following uses of the quantile() function would produce the correct interval bounds for a 96% bootstrap-based confidence interval? c(quantile(B$mean, 0.04), quantile(B$mean, 0.96)) c(quantile(B$mean, 0.02),…

For the given hypothesis test, explain the meaning of the kind of error, as requested. A statistics student has heard that about 25% of the students on his campus attend sporting events weekly. He wants to know if statistics students attend events in the same proportions as the general student body. Explain what the second type of error would be in this case (where the student fails to reject a null hypothesis that is actually false). O A. The second kind of error would be saying that statistics students attend sporting events in much higher proportions than the student body as a whole, even though they actually have the same attendence proportion. B. The second kind of error would be saying that there is no difference in the attendence of statistics students and the student body as a whole at sporting events, even though there really is. O C. The second kind of error would be saying that there is no difference in the attendence of statistics students and the student body as a whole at…
