- If a researcher decides to reject the null hypothesis using an alpha level of α = 0.05 at the conclusion of a hypothesis test, then they would include the statement of "p < 0.05" when writing their research report.Historically, 72% of students who take the PREPWell SAT preparation course improve their scores (where "improvement" denotes a score increase of at least 10 points). A new version of the PREPWell course is tested on a random sample of students, and 75% of them improve their scores. The PREPWell company is conducting a hypothesis test to determine whether the new version of the course actually gives better results. The hypotheses are H0: p = 0.72 Ha: p > 0.72 where p = the proportion of all students taking the new version of the PREPWell course that will improve their SAT scores For each description below, choose from the drop-down list to indicate which decision (A, B, or C) corresponds to it. (Each decision choice can be used once, more than once, or not at all.) Possible decisions: A. Reject the null hypothesis B. Do not reject the null hypothesis C. Accept the null hypotheses Even though the proportion of students with…Find the P-value for a left-tailed hypothesis test with a test statistic of z=−1.96. Decide whether to reject H0 if the level of significance is α=0.05.
- According to a restaurant owner, the percentage of kindergartners in the U.S. who say pancakes are their favorite food is less than 25%. Out of 200 randomly selected kindergartners who were surveyed, 45 said that pancakes are their favorite breakfast food. Using a complete test of hypothesis with a = 0.05 , is there enough evidence to support the claim of the restaurant owner? You may refer back to the previous problem for the steps required for a test of hypothesis.You conduct a poll of FIU students in order to determine the percentage of students (p) who agree with the statement “Hot-dogs are one of my favorite foods”. In your poll, you find that 80 out of 100 students agree. You conduct a two-sided hypothesis test where H0: p = 0.7, where p is the proportion of students whose favorite food is hot dogs. Compute the p-value.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=0.0411 (a) Do you reject or fail to reject Ho at the 0.01 level of significance? OA. Fail to reject Ho because the P-value, 0.0411, is greater than a = 0.01. OB. Fail to reject Ho because the P-value, 0.0411, is less than a =0.01. OC. Reject Ho because the P-value, 0.0411, is greater than a = 0.01. OD. Reject Ho because the P-value, 0.0411, is less than a = 0.01 (b) Do you reject or fail to reject Ho at the 0.05 level of significance? O A. Reject Ho because the P-value, 0.0411, is greater than a = 0.05. OB. Fail to reject Ho because the P-value, 0.0411, is less than a = 0.05. OC. Fail to reject Ho because the P-value, 0.0411, is greater than a = 0.05. O D. Reject Ho because the P-value, 0.0411, is less than a = 0.05. CECO

Decide whether to reject Ho if the level of significance is a =0.05.Explain whether or not rejecting the null hypothesis makes the alternative hypothesis true and why. If I conduct a hypothesis testing with Type I error set at 0.05 and a resulting p-value of 0.3, what would my conclusion be?The P-value for a hypothesis test is shown. Use the P-value to decide whether to reject H0 when the level of significance is (a) α=0.01,(b) α=0.05,and (c) α=0.10. (a) Do you reject or fail to reject H0 at the 0.01level of significance? A.
