Test the claim that the proportion of men who own cats is smaller than the proportion of women who own cats at the .025 significance level. The null and alternative hypothesis would be: Ho MMF Ho: PM = PF H₁: MMF O H₁: PM > PF O The test is: two-tailed right-tailed O The test statistic is: Based on a sample of 60 men, 25% owned cats Based on a sample of 40 women, 40% owned cats The p-value is: Ho: M = μF H₁: UM
MY NOTES Bags of a certain brand of tortilla chips claim to have a net weight of 12.5 oz. A representative of a consumer advocate group wishes to see if there is any evidence that the mean net weight is less than advertised and so intends to test the hypotheses H0: μ = 12.5, HA: μ < 12.5. To do this, he selects 24 bags of tortilla chips of this brand at random and determines the net weight of each. Data reveals a bell-shaped histogram, a sample mean of 12.31 ounces, and a standard deviation of 0.48 ounces.(a) What type of test is this? Two-sided, one-sample test Two-sided, two-sample test One-sided, two-sample test One-sided, one-sample test (b) Given the test statistic = -1.94 and α = 0.05, which of the following statements is the decision? Reject H0; conclude the bags are underweight. Fail to reject H0; do not conclude the bags are underweight. Fail to reject H0; conclude the the bags are underweight. Reject H0; conclude the bags are overweight.

K 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=0.0647 .. (a) Do you reject or fail to reject Ho at the 0.01 level of significance? OA. Reject Ho because the P-value, 0.0647, is greater than α=0.01. O B. Fail to reject Ho because the P-value, 0.0647, is less than α = 0.01. O C. Fail to reject Ho because the P-value, 0.0647, is greater than a = 0.01. OD. Reject Ho because the P-value, 0.0647, is less than a = 0.01. (b) Do you reject or fail to reject Ho at the 0.05 level of significance? OA. Fail to reject Ho because the P-value, 0.0647, is greater than α=0.05. OB. Reject Ho because the P-value, 0.0647, is greater than a = 0.05. OC. Reject Ho because the P-value, 0.0647, is less than a = 0.05. O D. Fail to reject Ho because the P-value, 0.0647, is less than a = 0.05. (c) Do you reject or fail to reject Ho at the 0.10 level of significance? 1
