I Need P-Value, Decision on the Null hypothesis, and Interpret the Result, answered thank you. Thank you. The population mean waiting time to check out of a supermarket has been 5 minutes. Recently, in an effort to reduce the waiting time,the supermarket has experimented with a system in which infrared cameras use body heat and in-store software to determine howmany lanes should be opened. A sample of 22 customers was selected, and their mean waiting time to check out was 4.31 minutes,with a sample standard deviation of 2.19 minutes. At the 0.1 significance level is there evidence that the population mean waiting timeto check out is less than 5 minutes?a. What are the null and alternate hypotheses?Ho: (Click to select) vH1: (Click to select) ♥ (Click to select) v(Click to select) v5b. What is the level of significance?(Round your answer to 2 decimal places.)c. Compute the value of the test statistic?sign in front of them)(Round your answer to 3 decimal places. Negative values should have a minusd. Determine the p-value(Round your final answer to 4 decimal places.)e. What is your decision regarding the null hypothesis?O Fail to reject the null.O Reject the null.f. Interpret the result.

True or false, explain: In a goodness-of fit test, if the p-value is 0.0153, in general, do not reject the null hypothesis.
Test the hypothesis using the P-value approach. Be sure to verify the requirements of the test. H0: p=0.72 versus H1: p≠0.72 n=500, x=350, a=0.01
A group of 250 patients was randomly split into two groups of 125 patients. The first group of 125 patients was given treatment A, and 72 of them improved their condition. The second group of 125 patients was given treatment B, and 60 of them improved their condition. Perform a hypothesis test to investigate whether there is evidence of a difference between the two treatments. What is the p-value of the test?

Q3 Test the given claim. Identify the null hypothesis, alternative hypothesis, test statistic, P-value, and then state the conclusion about the null hypothesis, as well as the final conclusion that addresses the original claim. Among 2125 passengers cars in a particular region, 229 had only rear license plates. Among 326 commercial trucks, 47 had only rear license plates. A reasonable hypothesis is that commercial trucks owners violate laws requiring front license plates at a higher rate than owners of passengers cars. Use a 0.01 significance level to test that hypothesis. A. Identity the nulls and alternative hypotheses B. Identify the test statistic ( round to two decimal places as needed) C. Identify the p- values (round to two decimal places as needed ? State the conclusion about the null hypothesis, as well as the final conclusion that addresses the original claim. A. Fail to reject Ho. There is not sufficient evidence to support the claim that commercial trucks owners…
Using traditional methods it takes 101 hours to receive an advanced driving license. A new training technique using Computer Aided Instruction (CAI) has been proposed. A researcher believes the new technique may lengthen training time and decides to perform a hypothesis test. After performing the test on 170 students, the researcher fails to reject the null hypothesis at a 0.10 level of significance. What is the conclusion?
Using the P-value method decide if you should reject the null hypothesis or not. In a sample of 81 adults selected randomly from one town, it is found that 8 of them have been exposed to a particular strain of the flu. At the 0.01 level of significance, you wish to test the proportion of all adults in the town that have been exposed to this strain of the flu is 8%
Imagine you are doing a Related-Samples t-test, and you are on Step Four of the hypothesis test. The study you are doing is testing whether there’s a significant difference between the anxiety of people before and after a final exam. The APA sentence is t(28) = 3.45, p < .05, d = 1.05. What is the correct set of conclusions that goes with this APA sentence? Group of answer choices Reject the H0, conclude that there IS a difference in anxiety, conclude based on effect size that the difference is small. Fail to Reject the H0, conclude that there IS a difference in anxiety. Reject the H0, conclude that there IS NOT a difference in anxiety, conclude based on effect size that the difference is small. Fail to Reject the H0, conclude that there IS NOT a difference in anxiety. Reject the H0, conclude that there IS a difference in anxiety, conclude based on effect size that the difference is large.
Using the P-value method decide if you should reject the null hypothesis or not. In a sample of 81 adults selected from one town, it is found that 8 of them have been exposed to a particular strain of the flu. At 0.01 level of significance, you wish to test the claim that the proportion of all adults in the town that have been exposed to this strain of the flu is 8%.
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=0.0596 (a) Do you reject or fail to reject Ho at the 0.01 level of significance? OA Fail to reject Hg because the P-value, 0.0596, is greater than a= 0.01. OB. Reject Ho because the P-value, 0.0596, is greater than a= 0.01. OC. Fail to reject Hg because the P-value, 0.0596, is less than a=0.01. %3D OD. Reject Ho because the P-value, 0.0596, is less than a= 0.01. %3D
