When are p-values negative ?
When the test statistic is negative
When the sample statistic is smaller than the proposed value of the
parameter
When the confidence interval includes only negative values
When we fail to reject the null hypothesis
Never
p - Value represents the probability of getting test statistic more extreme as the one in the sample when null hypothesis is true and a probability can never be negative. Hence,
The answer is Never.

A hypothesis test is performed at the α = 0.05 level of significance. The p-value is determined to be 0.03. Therefore, we know that we would _______________. either reject or fail to reject the null hypothesis, depending on the value of the test statistic. reject the null hypothesis know that a 99% confidence interval would contain the value specified in the null hypothesis. fail to reject the null hypothesis
How can I find a p-value when given a test statistic only with no df? I am preferably looking for a method with a TI-84 but will accept any answer, here is the question I am trying to answer: Use the given information to find the P-value. Also, use a 0.05 significance level and state the conclusion about the null hypothesis (reject the null hypothesis or fail to reject the null hypothesis). The test statistic in a left-tailed test is...
Which of the following is NOT a criterion for making a decision in a hypothesis test?Question content area bottomPart 1Choose the correct answer below.A.If the test statistic falls within the critical region, the decision is to reject the null hypothesis.B.If P-value≤α, the decision is to reject the null hypothesis. Otherwise, we fail to reject the null hypothesis.C.If the P-value is less than 0.05, the decision is to reject the null hypothesis. Otherwise, we fail to reject the null hypothesis.D.If a...
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 2158 passenger cars in a particular region, 249 had only rear license plates. Among 330 commercial trucks, 46 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 passenger cars....
For each problem, select the correct response. (a) What is the P-value of a test of the null hypothesis? A. The probability the null hypothesis is false B. The probability, assuming the null hypothesis is false, that the test statistic will take a value at least as extreme as that actually observed C. The probability the null hypothesis is true D. The probability, assuming the null hypothesis is true, that the test statistic will take a value at least as...
A P-value of 0.12 is calculated on a hypothesis test with a significance level set at 0.01. Which of the following is the correct conclusion for the test? a. Claim the null hypothesis is true b. Fail to reject the null hypothesis c. Reject the null hypothesis d. Claim the alternative hypothesis is true Which of the following are not requirements for using the t-distribution for a hypothesis test concerning μ? (More than one answer may be correct.) a. Sample...
The test statistic of z equals negative 1.89 is obtained when testing the claim that p less than0.14. a. Using a significance level of alpha equals0.10, find the critical value(s). b. Should we reject Upper H 0 or should we fail to reject Upper H 0?
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 2135 passenger cars in a particular region, 241 had only rear license plates. Among 391 commercial trucks, 59 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 passenger cars....
(c)What is the test statistic? Give your answer to 3 decimal places. 5.971 (d)The p-value = 0.005. Which of the following is an appropriate conclusion? The data provides very strong statistical evidence that the average SENS reading after antihypertensive treatment is lower than the average SENS reading before antihypertensive treatment. The data does not provide statistical evidence that the the average SENS reading after antihypertensive treatment is lower than the average SENS reading before antihypertensive treatment. The data provides very...
QUESTION 21 A p value is the probability of obtaining the value of the test statistic or more extreme, if the null hypothesis is true. a. True b. False QUESTION 18 Type I error occurs when a. you reject a false null hypothesis b. you reject a true null hypothesis c. you fail to reject a false null hypothesis d. you fail to reject a true null hypothesis QUESTION 19 Type II error occurs when a. you reject a false...
