For a hypothesis test, alpha = 0.05 %3! The computed P-Value = 0.011 Should HO be rejected?: O Fail to Reject H_0 O Reject H_0 What is the correct conclusion? OThere IS sufficient evidence to reject the Null Hypothesis and accept the alternative. OThere is NOT sufficient evidence to reject the Null Hypothesis and accept the alternative.

If, in a sample of n = 25 selected from a normal population, X = 57 and S= 10, what is the value of tSTAT if you are testing the null hypothesis Ho: μ = 50? tSTAT = (Type an integer or a decimal.)

Suppose that we have a problem for which the null and alternative hypothesis are given by: H0: μ = $1250. H1:μ ≠ $ 1250 Is this a right-tailed test, left-tailed test, or two-tailed test. Find the z value based on a level of significance of α=.12.

If, in a sample of n = 16 selected from a normal population, X= 51 and S = 8, what is the value of tSTAT if you are testing the null hypothesis Ho: µ= 50? tSTAT = (Type an integer or a decimal.)

In a given hypothesis test, the null hypothesis can be rejected at the 0.10 and the 0.05 level of significance, but cannot be rejected at the 0.01 level. The most accurate statement about the ?−p−value for this test is: A. ?-value=0.10p-value=0.10 B. 0.01<?-value<0.050.01<p-value<0.05 C. 0.05<?-value<0.100.05<p-value<0.10 D. ?-value=0.01p-value=0.01

Let p be the propotion of seniors who will play bingo. Based on a random sample of 175 seniors, 103 of them have said that they will play bingo. Using this data, test the null hypothesis that p=.5 versus the alternative that p>.5 at the alpha = .1 level. What is the p-value and conclusion of this test? Should you reject or fail to reject the hypothesis?

Find the​ P-value for a​ left-tailed hypothesis test with a test statistic of Z=−1.65. Decide whether to reject H0 if the level of significance is α=0.05 ​P-value= ​(Round to four decimal places as​ needed.)

A police office claims that the proportion of people wearing seat belts is less than 65%. To test this claim, a random sample of 200 drivers is taken and its determined that 126 people are wearing seat belts. The following is the setup for this hypothesis test: Ho :p-0.65 Ha : p < 0.65 In this example, the p-value was determined to be 0.277 come to a conclusion and interpret the results for this hypothesis test for a proportion (use a significance level of 5%) Select the correct answer below: O The decision is to reject the Null Hypothesis. The conclusion is that there is enough evidence to support the claim The decision is to fail to reject the Null Hypothesis. The conclusion is that there is not enough evidence to support the claim

19% of all college students volunteer their time. Is the percentage of college students who are volunteers smaller for students receiving financial aid? Of the 338 randomly selected students who receive financial aid, 44 of them volunteered their time. What can be concluded at the α = 0.05 level of significance? a. For this study, we should use Select an answer b. The null and alternative hypotheses would be: (please enter a decimal) Please enter a decimal) c. The test statistic (please show your answer to 3 decimal places.) 2 (Please show your answer to 4 decimal places.) d. The p-value e. The p-value is? a f Based on this, we should Select an answer g. Thus, the final conclusion is that the null hypothesis. The data suggest the population proportion is not significantly lower than 19% at α-0.05, so there is insufficient evidence to conclude that the percentage of financial aid recipients who volunteer is lower than 1996. The data suggest the population proportion is not significantly…

Does training in stress reduction make a difference for student success?  15 students received training (M1= 88, SS1= 400) and 15 students did not (M2= 82, SS2= 440). Test using α = .05   Which is the null hypothesis, H0?
