Question

The probability of a Type I error is denoted by C. a d, 1-α b. 1-B a. b. c. d. A Type I error is committed if we make a correct decision when the null hypothesis is false a correct decision when the null hypothesis is true an incorrect decision when the null hypothesis is false. an incorrect decision when the null hypothesis is true 6. a. b. c. d. A Type Il error is committed if we make: a correct decision when the null hypothesis is false a correct decision when the null hypothesis is true an incorrect decision when the null hypothesis is false. an incorrect decision when the null hypothesis is true A spouse suspects that the average amount of money spent on Christmas gifts for immediate family members is above $1,200. The correct set of hypotheses is a. Ho: μ-1200 vs. H1: μ < 1200 b, Ho: μ > 1200 vs. H1: μ-1200 C. Ho: H 1200 vs. Hi: H> 1200 d. Ho: μ < 1200 vs. H1: μ-1200 8. a. b. A Type I error occurs when we reject a false null hypothesis. reject a true null hypothesis. c. d. don't reject a false null hypothesis. don't reject a true null hypothesis The probability of a Type Il error is denoted by: a. a C. d. 1-B
