1. Suppose that we are testing Hor = po versus H : > Ho with a sample size of n = 15. Calculate bounds on the P-value for the following observed values of the test statistic: (a) to = 2.35 (b) to = 3.55 (c) to = 1.55
The test statistic of z=−3.11 is obtained when testing the claim that p <0.72. a. Using a significance level of alpha=0.01, find the critical value(s). b. Should we reject H0 or should we fail to reject H0 and is the evidence insufficient or sufficient?
What is the critical value?? The test statistic of z = -2.04 is obtained when testing the claim that p<0.32. a. Using a significance level of a = 0.01, find the critical value(s). b. Should we reject Ho or should we fail to reject Ho? Click here to view page 1 of the standard normal distribution table. Click here to view page 2 of the standard normal distribution table. a. The critical value(s) is/are z = (Round to two decimal...
Suppose that you are testing the following hypotheses: Ho: = 10 and 11: > 10. If the null hypothesis is rejected at the 1% level of significance, what statement can you make about the confidence interval on the mean? a) The lower bound of a 95% one-sided confidence interval on the mean exceeds 10. b) 9 sus 13 c) No statement can be made. d) The lower bound of a 95% one-sided confidence interval on the mean exceeds zero. If...
In testing H0: μ = 10 vs Ha: μ 6= 10, we find the test z-statistic is z(obs) = −2.5 Find the P-value of the test.
The test statistic of z = 2.53 is obtained when testing the claim that p*0.112. a. Identify the hypothesis test as being two-tailed, left-tailed, or right-tailed. b. Find the P-value. c. Using a significance level of a= 0.05, should we reject Hor should we fail to reject Ho? Click here to view page 1 of the standard normal distribution table. Click here to view page 2 of the standard normal distribution table. a. This is a test b. P-value =...
. We would like to conduct a hypothesis test at the 10% level of significance to determine whether the true mean score of all players in a bowling league differs from 150. The mean and standard deviation of the scores of 12 randomly selected players are calculated to be 170 and 16, respectively. Scores of all players in the league are known to follow a normal distribution. The P-value of the appropriate test of significance is
Bonus (5 points) Suppose that you are testing the following hypotheses: Ho: 4 = 10 and H :> 10. If the null hypothesis is rejected at the 1% level of significance, what statement can you make about the confidence interval on the mean? a) The lower bound of a 95% one-sided confidence interval on the mean exceeds 10. b) 9 <u< 13 c) No statement can be made. d) The lower bound of a 95% one-sided confidence interval on the...
To determine significance of a statistical test, we use p-value to help us make the decision. To determine the significance, we look to see if the p‐value is... Question options: greater than 0.05 between 0.01 and 0.05 less than 0.01 greater than 0.01
Suppose we are testing Ho: p=.20 vs Ha: p<.20 and TS=2.34. What is the p-value? 0.0096 0.9904 0.0107 0.0192 0.9893 0.0214
