a. Explain what it would mean to make a type I error. O A. A type I error would occur if in fact u > 20 mg, but the results of the sampling fail to lead to the conclusion that u = 20 mg. B. A type I error would occur if in fact u = 20 mg, but the results of the sampling fail to lead to the conclusion that u > 20 mg. C. A type I error would occur if in fact u = 20 mg, but the results of the sampling lead to the conclusion that u > 20 mg. b. Explain what it would mean to make a type II error. A. A type ll error would occur if in fact u > 20 mg, but the results of the sampling lead to the conclusion that u > 20 mg. B. A type ll error would occur if in fact u > 20 mg, but the results of the sampling fail to lead to the conclusion that u > 20 mg. O C. A type II error would occur if in fact u = 20 mg, but the results of the sampling lead to the conclusion that u > 20 mg. c. Explain what it would mean to make a correct decision. O A. A correct decision would occur if u = 20 mg and the results of the sampling do not lead to the rejection of that fact; or if u > 20 mg and the results of the sampling lead to that conclusion. O B. A correct decision would occur if u # 20 mg and the results of the sampling lead to the rejection of that fact; or if u = 20 mg and the results of the sampling do not lead to that conclusion. C. A correct decision would occur if u = 20 mg and the results of the sampling lead to the rejection of that fact; or if u > 20 mg and the results of the sampling do not lead to that conclusion. d. Now suppose that the results of carrying out the hypothesis test lead to rejection of the null hypothesis. Classify that conclusion by error type or as a correct decision if in fact the mean iron intake of all adult females under the age of 51 equals the RDA of 20 mg per day. O A. type ll error B. correct decision O C. type | error e. Suppose that the results of carrying out the hypothesis test lead to rejection of the null hypothesis. Classify that conclusion by error type or as a correct decision if in fact the mean iron intake of all adult females under the age of 51 is greater than the RDA of 20 mg per day. O A. type I error B. correct decision Time Remaining: 01:55:03 Next
