In testing hypotheses, if the consequences of failing to reject a null hypothesis that is actually false are very serious, we should: A. use a very small level of significance. B. use a very large level of significance. C. insist that the level of significance be smaller than theP-value D. insist that theP-value be smaller than the level of significance. ( don't hand writing solution)

Suppose that for a particular hypothesis test, the consequences of a Type I error are very serious. Would you want to carry out the test using a small significance level a (such as 0.01) or a larger significance level (such as 0.10)? Explain the reason for your choice. The probability of a Type I error is equal to the significance level, so a larger significance level should be used. O The probability of a Type I error is equal to one minus the significance level, so a larger significance level should be used. The probability of a Type I error is equal to one minus the significance level, so a small significance level should be used. The probability of a Type I error is equal to the significance level, so a small significance level should be used.

please answer last three subparts. thank you!!
Which of the following statements are TRUE? I. Increasing the significance level of a test will increase the chance of erroneously rejecting a true null hypothesis. II. Increasing the significance level of a test will increase the chance of erroneously failing to reject a false null hypothesis. Only statement I is true. Neither statement is true. Only statement II is true. Both statements are true.

Suppose that a hypothesis test is performed at a small significance level. State the appropriate conclusion in each case by referring to Key Fact 2. a. The null hypothesis is rejected.b. The null hypothesis is not rejected.
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
A hypothesis test was used to test the hypothesis that people with a significant other are happier on average than people without. The P-value was 0.07 and the level of significance used was 0.1. Then there is sufficient evidence to conclude that, on average, people with a significant other are happier than single people. True or False
