Transcribed Image Text:Assume that the amounts of weight that male college students gain during their freshman year are normally distributed with a mean of 12 g and a standand devtion of e57kg Complete parts atvh i telon
A1 male college student in randomly selected, find the probabilty that he gains between O kg and 3 kg during trostman year
The probabity in
(Round to four deoimal places as needed.)
b. If o male college students are randonty selected, find the probability that their mean weight gain during frestman year is between 0 kg nd 3 g
The probability ia
(Round to four decimal places as needed)
e Why can the nomal distribution be used in part (b), even though the sampie size does not exceed 307
OA Bince the distribution is of individuals, not sampie meana, the distribution in a nomal distribution for any sample sie
OR Since the weight gain exceeds 30, the dietribuion of sample means is a normal distribution for any sample s
OC Bince the original population has a normal distribution, the distribution of sample means isa nomal disbribution for any ample size.
OD. Bince the distritution ie of sample meane, not individuals, the distribution ia normal dstribution for any sample se
