Find the P-value for a left-tailed hypothesis test with a test statistic of z= -1.23. Decide whether to reject Ho if the level of significance is a = 0.10. P-value = (Round to four decimal places as needed.) State your conclusion. Choose the correct answer below. Since P> α, reject Ho- Since P ≤ a, fail to reject Ho- Since P > a, fail to reject Ho- O Since P ≤a, reject Ho.

Suppose you are conducting a hypothesis test and you find a P-value of .17. Is there sufficient evidence at a=0.10 to reject the Null Hypothesis? O not enough information to make a conclusion O yes O no

The average wait time to get seated at a popular restaurant in the city on a Friday night is 13 minutes. Is the mean wait time less for men who wear a tie? Wait times for 16 randomly selected men who were wearing a tie are shown below. Assume that the distribution of the population is normal. 11, 14, 14, 14, 13, 13, 10, 11, 10, 10, 12, 10, 12, 14, 13, 11 What can be concluded at the the a = 0.05 level of significance level of significance?

Suppose there is a claim that a certain population has a mean, u, that is different than 7. You want to test this claim. To do so, you collect a large random sample from the population and perform a hypothesis test at the 0.10 level of significance. To start this test, you write the null hypothesis, Ho, and the alternative hypothesis, H, as follows. Ho: H=7 H: u#7 Suppose you also know the following information. The value of the test statistic based on the sample is - 1.845 (rounded to 3 decimal places). The p-value is 0.065 (rounded to 3 decimal places). (a) Complete the steps below for this hypothesis test. O Two-tailed Step 2: Enter the test statistic. (Round to 3 decimal places.) 0.3 Step 3: Shade the area represented by the p- value. 0.2 Step 4: Enter the p- value. (Round to 3 decimal places.) (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…

The following hypotheses are given. Ho:πT≤ 0.83 H₁: TT> 0.83 A sample of 100 observations revealed that p = 0.87. At the 0.10 significance level, can the null hypothesis be rejected? a. State the decision rule. (Round your answer to 2 decimal places.) Reject Ho if z> b. Compute the value of the test statistic. (Round your answer to 2 decimal places.) Value of the test statistic c.

Suppose are running a study/poll about the proportion of voters who prefer Candidate A. You randomly sample 102 people and find that 70 of them match the condition you are testing.Suppose you are have the following null and alternative hypotheses for a test you are running:H0:p=0.68Ha:p<0.68Calculate the test statistic, rounded to 3 decimal places z=

Find the P-value for a left-tailed hypothesis test with a test statistic of z = - 1.68. Decide whether to reject H, if the level of significance is a= 0.10. P-value = (Round to four decimal places as needed.) State your conclusion. Choose the correct answer below. O Since P>a, fail to reject Ho- O Since P>a, reject Ho- O Since Psa, fail to reject Ho- OS ince Psa, reject Ho-

Describe type I and type II errors for a hypothesis test of the indicated claim. A furniture store claims that at least 40% of its new customers will return to buy their next piece of furniture. Describe the type I error. Choose the correct answer below. OA. A type I error will occur when the actual proportion of new customers who return to buy their next piece of furniture is at least 0.40, but you fail to reject Ho: p20.40. OB. A type I error will occur when the actual proportion of new customers who return to buy their next piece furniture is at least 0.40, but you reject Ho: p20.40. OC. A type I error will occur when the actual proportion of new customers who return to buy their next piece of furniture is no more than 0.40, but you reject Ho: p ≤ 0.40. OD. A type I error will occur when the actual proportion of new customers who return to buy their next piece f furniture is no more than 0.40, but you fail to reject Ho: p ≤0.40. Describe the type II error. Choose the correct answer…
