This test: 20 point(s) possible E Test: Final Exam Question 20 of 20 Submit test This question: 1 point(s) possible Assume that the amounts of weight that male college students gain during their freshman year are normally distributed with a mean of p :1 4 kg and a standard deVIation ofo : 5 6 kg, Complete pars (a) through (c) below a. |f1 male college student is randomly selected, nd the probability that he gains between 0 kg and 3 kg during freshman year The probability is U 5357 (Round to four decimal places as needed ) b. If 4 male college students are randomly selected, nd the probability that their mean weight gain during freshman year is between 0 kg and 3 kg. The probability is , (Round to four decimal places as needed ) 0. Why can the normal distribution be used in part (b), even though the sample size does not exceed 30? O A. Since the original population has a normal distribution, the distribution of sample means is a normal distribution [or any sample size O B. Since the weight gain exceeds 30, the distribution of sample means is a normal distribution for any sample size, 0 (3. Since the distribution is of indiwduals, not sample means, the distribution is a normal distribution for any sample size O D. Since the distribution is of sample means, not indiVIduals, the distribution is a normal distribution for any sample size Tutoring Help me solve this Get more help - Sub test
