A cell phone salesperson selects a random sample of 75 customers. For each customer, he records which cell phone provider (A, B, or C) they use and the type of phone they purchase. He would like to know whether there is convincing evidence that a customer’s cell phone provider is associated with the type of cell phone the customer purchases. Let = 0.05. What are the hypotheses for this test? H0: Type of cell phone is not independent of the cell phone provider.Ha: Type of cell phone is independent of the cell phone provider. H0: Type of cell phone is independent of the cell phone provider.Ha: Type of cell phone is not independent of the cell phone provider. H0: The proportion of types of phones differs for cell phone providers.Ha: The proportion of types of phones equals in cell phone providers. H0: There is an association between type of cell phone and the cell phone provider.Ha: There is no association between type of cell phone and the cell phone provider.
The null and alternate hypotheses are: He: T1 T₂ H₁: T₁ T₂ A sample of 100 observations from the first population indicated that x₁ is 70. A sample of 150 observations from the second population revealed x₂ to be 90. Use the 0.05 significance level to test the hypothesis. a. State the decision rule. (Round your answer to 2 decimal places.) HO is rejected if z> b. Compute the pooled proportion. (Round your answer to 2 decimal places.) Pooled proportion

An opinion poll asked a random sample of adults whether they believe flu shots are ineffective in the United States. A commentator believes less than 35% of all adults believe they are ineffective. Which null and alternative hypotheses should be used to test this claim? Group of answer choices H0: p ≠ 0.35, Ha: p < 0.35 H0: p = 0.35, Ha: p < 0.35 H0: p = 0.35, Ha: p ≠ 0.35 H0: p < 0.35, Ha: p = 0.35 H0: p = 0.35, Ha: p > 0.35
. If a hypothesis test is a two-tailed test and the test statistic is t = 2.687 when n = 19, what is the P-value of the test? Must also show picture with degrees of freedom.
Suppose the null hypothesis, Ho, is: the mean age of the horses on a ranch is 6 years. What is the Type lI error in this scenario? Select the correct answer below: O O O O You think the mean age of the horses on a ranch is 6 years when, in fact, it is. You think the mean age of the horses on a ranch is 6 years when, in fact, it is not. You think the mean age of the horses is not 6 years when, in fact, it is. You think the mean age of the horses is not 6 years when, in fact, it is not.
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…
suppose a hypothesis test is conducted where the level of significance a= 0.05 and the test results in p- value = 0.04 should the researcher reject the null hypothesis? A. yes because the p-value is less than a b. no should not reject because the p-value is greater than a c. no should not reject because is less than a d. yes should reject because the p-value is greater than a
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) a = 0.01, (b) a = 0.05, and (c) a=0.10. P=0.0411 (a) Do you reject or fail to reject Ho at the 0.01 level of significance? OA. Fail to reject Ho because the P-value, 0.0411, is greater than a = 0.01. OB. Fail to reject Ho because the P-value, 0.0411, is less than a =0.01. OC. Reject Ho because the P-value, 0.0411, is greater than a = 0.01. OD. Reject Ho because the P-value, 0.0411, is less than a = 0.01 (b) Do you reject or fail to reject Ho at the 0.05 level of significance? O A. Reject Ho because the P-value, 0.0411, is greater than a = 0.05. OB. Fail to reject Ho because the P-value, 0.0411, is less than a = 0.05. OC. Fail to reject Ho because the P-value, 0.0411, is greater than a = 0.05. O D. Reject Ho because the P-value, 0.0411, is less than a = 0.05. CECO
