Original claim: More than 55% of adults would erase all of their personal information online if they could. The hypothesis test results in a P-value of 0.0179. ... a. State a conclusion about the null hypothesis. (Reject H, or fail to reject H) Choose the correct answer below. O A. Reject H, because the P-value is less than or equal to a. O B. Fail to reject H, because the P-value is less than or equal to a. O C. Reject Ho because the P-value is greater than a. OD. Fail to reject H, because the P-value is greater than a. b.

- QUESTION 2 What is a Type II error? O Retaining the null with the null is true. O Rejecting the null when the null is true. Retaining the null when the null is false. O Rejecting the null when the null is false.Can someone help me understand these two questions I'm not sure how to find the answers? An independent-samples research study uses two samples, each with n = 12 participants. If the data produce a t-statistic of t = 2.50, then which of the following is the correct decision for a two-tailed hypothesis test? Reject the null hypothesis with α = .05 but fail to reject with α = .01. Reject the null hypothesis with either α = .05 or α = .01. Fail to reject the null hypothesis with either α = .05 or α = .01. Fail to reject the null hypothesis with α = .01, but reject the null with α = .05. The results of an independent-samples study are reported as “t (20) = 2.12, p < .05, two-tailed.” For this study, what tcritical values form the boundaries for the critical region? ± 2.093 ± 2.086 ± 2.080 ± 2.074For the next items, identity the appropriate statistical test that will be utilized in hypothesis testing.
