A researcher runs a one-sample, one-sided t-test, and finds that t = 1.93, df = 21, α = .05, where: H 0: μ = 12 H 1: μ > 12 What decision should be made regarding the hypothesis? -Reject the null hypothesis. -Reject the alternative hypothesis. -Fail to reject the null hypothesis. -Fail to reject the alternative hypothesis.
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...
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
Question 21 (4 points) 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). With H1: p. 0.612, the test statistic is z = -3.06. 1) 0.0022; fail to reject the null hypothesis 2) 0.0011; fail to reject the null hypothesis 3) 0.0011; reject the null hypothesis 4) 0.0022; reject the null hypothesis
If the p value for a hypothesis test is 0.0271, which would be a correct decision? Do not reject the null hypothesis when alpha is 0.10. Do not reject the null hypothesis when alpha is 0.05. Reject the null hypothesis when alpha is 0.025. Reject the null hypothesis when alpha is 0.10. none of the above
IPS 19 When testing for independence, what decision/conclusion can we make when the P-value is 0.03 and the significance level is 0.05? Enough evidence to conclude that the two variables are independent Reject the alternative hypothesis Enough evidence to conclude that the two variables are dependent Reject the null hypothesis
Select the p-value(s) at which you would reject the null hypothesis for a two-sided test at the 90% confidence level. SELECT ALL THAT APPLY. 0.9500 0.9000 0.8900 0.1100 0.0900 0.0500 0.0250
Question 3 Not yet answered Marked out of 3.00 P Plas question If your alpha is 0.05, and the p-value from your test is 0.06, then your decision will be to Select one: a. Fail to reject the null hypothesis b. Fail to reject the alternative hypothesis c. Reject the null hypothesis d. Reject the alternative hypothesis
Score. b. Question 6 B0/3 pts 399 Det Test the claim that the mean GPA of night students is larger than 3.5 at the 0.025 significance level. The null and alternative hypothesis would be: H:p = 0.875 H :p > 0.875 HH <3.5 H: > 3.5 H: = 3.5 H :P < 0.875 HP 0.875 H :P < 0.875 H: > 3.5 H: < 3.5 H1: +3.5 H :p > 0.875 The test is: right-tailed two-tailed left-tailed Based on a...
The P-value for a hypothesis test is shown. Use the P-value to decide whether to reject H when the level of significance is (a) a= 0.01, (b) a 0.05, and (c) a0.10. P 0.0749 (a) Do you reject or fail to reject Ho at the 0.01 level of significance? O A. Reject H because the P-value, 0.0749, is greater than a=0.01 O B. Fail to reject Ho because the P-value, 0.0749, is less than a = 0.01 O C. Reject...
