Identify the null and alternative hypotheses for this test. Choose the correct answer below. O A. Ho: p#0.513 H1: p= 0.513 О в. Но р3D0.513 H1:p>0.513 С. Но: р3D 0.513 H4:p#0.513 O D. Ho:p= 0.513 H1:p<0.513 Identify the test statistic for this hypothesis test. The test statistic for this hypothesis test is. (Round to two decimal places as needed.)

Which of the following is not one of the four steps of the hypothesis test? A. State the level of significance, choose a test, and check the conditions for the test B. Make a decision to reject or not reject the null hypothesis  C. State the null and alternative hypothesis about the population parameter D. All of the these are steps of the hypothesis test

B. Identify the test statistic. z=___ C. Identify the​ P-value. ​P-value=___   D. What is the conclusion based on the hypothesis​ test?  The​ P-value is (greater than/ less than) the significance level of α=0.05​, so (reject/ fail to reject) the null hypothesis. There (suffiecient/ is not sufficient) evidence to warrant rejection of the claim that women and men have equal success in challenging calls.   Test the claim by constructing an appropriate confidence interval. The 95​% confidence interval is___<(p1-p2)<____.   E. What is the conclusion based on the confidence​ interval? Because the confidence interval limits (include/ do not include) 0, there (does/ does not) appear to be a significant difference between the two proportions. There (is sufficient/ is not sufficient) evidence to warrant rejection of the claim that men and women have equal success in challenging calls.   F. Based on the​ results, does it appear that men and women may have equal success in challenging​…

Perform the test of hypothesis on the following scenarios. A brand of powdered milk is advertised as having a net weight of 250 grams. A curious consumer obtained the net weight of 10 randomly selected cans. The values obtained are 256, 248, 242, 245, 246, 248, 250, 255, 243, and 249 grams. Is there reason to believe that the average net weight of the powdered milk cans is less than 250 grams at 10% level of significance? Assume the net weight is normally distributed with unknown population variance. Note: pls follow the given steps in the photo attached

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) α = 0.01, (b) α = 0.05, and (c) α = 0.10. P = 0.0176 (a) Do you reject or fail to reject Ho at the 0.01 level of significance? A. Reject Ho because the P-value, 0.0176, is less than α = 0.01. B. Reject Ho because the P-value, 0.0176, is greater than α = 0.01. C. Fail to reject Ho because the P-value, 0.0176, is greater than α = 0.01. D. Fail to reject Ho because the P-value, 0.0176, is less than α = 0.01. (b) Do you reject or fail to reject Ho at the 0.05 level of significance? A. Fail to reject Ho because the P-value, 0.0176, is less than α = 0.05. B. Reject Ho because the P-value, 0.0176, is greater than α = 0.05. C. Reject Ho because the P-value, 0.0176, is less than α = 0.05. D. Fail to reject Ho because the P-value, 0.0176, is greater than α = 0.05. (c) Do you reject or fail to reject Ho at the 0.10 level of significance? A. Fail to reject Ho because the…

7. Question: The power of a test is measured by its capability of: a. Accepting a null hypothesis that is true. b. Rejecting a null hypothesis that is true. c. Rejecting the alternative hypothesis that is false. d. Rejecting a null hypothesis that is false. e. None of the mentioned.

The mean IQ of statistics teachers is greater than 130. Identify the type I and type II errors for the hypothesis test of this claim.   Rejecting or failing to reject Ho: μ ≤ 130 when μ ≤ 130 Rejecting or failing to reject Ho: μ ≤ 130 when μ > 130

According to a recent study in New York, 15% of shoppers are unfairly being charged sales tax in non-taxable items.  Mr. Hypothesis feels this proportion is too low.  He tests his belief by conducting a survey of 200 random shoppers. Which of the following is the null hypothesis?   a. The percent of shoppers unfairly being charged sales tax on non-taxable items < .15   b. The percent of shoppers unfairly being charged sales tax on non-taxable items > .15   c. The percent of shoppers unfairly being charged sales tax on non-taxable items = .15
