D Question 23 3 pts The number of eggs laid by a hen in a year is normally distributed with a mean of 298 and a standard deviation of 12.5. In a random sample of 100 hens, the number of eggs produced per year was recorded and the mean calculated. Describe the sampling distribution of the sample mean. O Approximately normal with mean u = 298 and standard deviation o = 12.5 O Shape unknown with mean u = 2.98 and standard deviation o = 0.0125 O Approximately normal with mean u = 298 and standard deviation o = 1.25 O Shape unknown with mean u = 2.98 and standard deviation o = 0.125 O Not enough information is given to determine the distribution of the sample mean
