Question 6: A hypothesis test results in the rejection of the null hypothesis at significance level a-0.05. What is the result if the test is redone at significance level a=0.01, with all other test parameters remaining the same? (a) The null hypothesis is still rejected with a higher power value (b) The null hypothesis is still rejected with a lower power value (c) The null hypothesis may not be rejected with a higher power value (d) The null hypothesis may not be rejected with a lower power value

It has recently been claimed that 25% of adults consider spring to be their favorite season of the year. A researcher is skeptical of this claim and believes this percentage is too low. She surveys a random of 1,000 adults and finds that 390 of these adults consider spring to be their favorite season of the year. As she prepares to conduct a hypothesis test, the researcher writes out her alternative hypothesis as “p < 0.25.” What is wrong with this? The alternative hypothesis should be “p > 0.39.” The alternative hypothesis should be “p < 0.39.” The alternative hypothesis should be “p > 0.25.” The alternative hypothesis should be “p = 0.25.” Nothing is wrong with the given alternative hypothesis.
This is part 'd' that isn't included in the picture. (d)Based on your answer to part (c), choose what can be concluded, at the 0.05 level of significance, about your claim. Since the p-value is less than (or equal to) the level of significance, the null hypothesis is rejected. So, there is enough evidence to support the claim that the percentage of software engineers who rate the company they work for as "a great place to work" is not 92% . Since the p-value is less than (or equal to) the level of significance, the null hypothesis is not rejected. So, there is not enough evidence to support the claim that the percentage of software engineers who rate the company they work for as "a great place to work" is not 92% .

A sports league performs a hypothesis test at the 0,10 level of significance to determine if the proportion, p, of all times a certain referee's coin comes up heads when flipped is different from 50%. Here are the null hypothesis Hg and the alternative hypothesis H, for the test. Hạ p-0.5 00 Hi p+0,5 (a) The resuit of the league's hypothesis test will be to either reject or not reject the null hypothesis, H Based on whether H is in fact true or is in fact false, fil in the table below to indicate whether the result of the test is correct, a Type i error, or a Type il error. H, is true H, is talse Reject H, (Choose one) (Choose one) Do not reject H. (Choose one) (Choose one) (b) The league takes a random sample and determines it is appropriate to use a Z test.

Question 5: what is the conclusion?
In a given hypothesis test, the null hypothesis cannot be rejected at the 0.005 and the 0.01 level of significance, but can be rejected at the 0.03 level. The most accurate statement about the p- value for this test is: O A. p-value 0.03
If the p-value is very large (say close to 1), then it is likely that we will reject the null hypothesis. True False
(b)Based on your answer to part (a), which statement below is true? Since the p-value is less than (or equal to) the level of significance, the null hypothesis is rejected. Since the p-value is less than (or equal to) the level of significance, the null hypothesis is not rejected. Since the p-value is greater than the level of significance, the null hypothesis is rejected. Since the p-value is greater than the level of significance, the null hypothesis is not rejected.
A refrigerator manufacturer claims that the mean life of its competitor's refrigerators is less than 16 years. You are asked to perform a hypothesis test to test this claim. (a) How would you write the null and alternative hypothesis if you represent the manufacturer and want to support the claim? (b) How would you write the null and alternative hypothesis if you represent the competitor and want to reject the claim? (a) Ho Ha ▼ 16 16
7. 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) α = 0.01, (b) x = 0.05, and (c) α = 0.10. P = 0.1176 (a) Do you reject or fail to reject Hå at the 0.01 level of significance? O A. Fail to reject Ho because the P-value, 0.1176, is greater than α = 0.01. Reject Hå because the P-value, 0.1176, is greater than α = 0.01. O B. O C. Fail to reject Ho because the P-value, 0.1176, is less than α = 0.01. O D. Reject Ho because the P-value, 0.1176, is less than α = = 0.01. (b) Do you reject or fail to reject Ho at the 0.05 level of significance? O A. Fail to reject Ho because the P-value, 0.1176, is less than α = 0.05. B. Fail to reject Ho because the P-value, 0.1176, is greater than α = 0.05. O C. Reject Ho because the P-value, 0.1176, is greater than α = = 0.05. D. Reject Ho because the P-value, 0.1176, is less than α = = 0.05.
