It is the probability of committing type I error and it is the smallest significant level at which a null hypothesis would be rejected B. It is the probability of committing type I error and it is the largest significant level at which a null hypothesis would be rejected C.

Which of the following is NOT true about the level of significance of a hypothesis test?...
Which of the following is NOT true about the level of significance of a hypothesis test? The larger the significance, the higher the risk that we make an error The level of significance is the maximum risk we are willing to accept in making an error. The significance level is also called the α level The significance level is determined by your sample size

State whether the following statements true or false, and Why? 1. The type I error and type II error are related. A decrease in the probability of one generally results in an increase in the probability of the other. 2. The size of the critical region, and therefore the probability of committing a type I error, can always be reduced by adjusting the critical value(s). 3. An increase in the sample size n will reduce α and β simultaneously. 4....

α is the probability of a Type I error, which occurs when we accept the alternative H1 when the null hypothesis Ho is true. True False A Type II error occurs when when a false null hypothesis is rejected. True False If a null hypothesis is rejected at the 5% significance level but not at the 1% significance level, then the p-value of the test is less than 1%. True False The power of a test is the probability of...

Which of the following statements is FALSE? a.) The power of a hypothesis test is the probability of not making a Type II error. b.) Alpha (α) is equal to the probability of making a Type I error. c.) The probability of rejecting the null hypothesis when the null hypothesis is true is called a Type I Error. d.) A smaller sample size would increase the effectiveness of a hypothesis test.

These are all True & False Questions. Just write the number and T/F 6. If we reject the null hypothesis, we can conclude that the sample differs from the population mean. T/F 7. Type II error occurs when we set α to high. T/F 8. The alpha level determines the risk of Type I error. T/F 9. In a two-tailed test, you need more evidence to reject the null hypothesis. T/F 10.
