An IQ test is designed so that the mean is 100 and the standard deviation is 19 for the population of normal adults. Find the sample size necessary to estimate the mean IQ score of statistics students such that it can be said with 99% confidence that the sample mean is within 6 IQ points of the true mean. Assume that o = 19 and determine the required sample size using technology. Then determine if this is a reasonable sample size for a real world calculation. The required sample size is (Round up to the nearest integer.)

Choose the corect answer below.
A. The proportion of even numbers in tht population is equal to the mean of the sample proportions.
B. The proportion of even numbers in the population is not equal to the mean of the sample proportions.
OC. The proportion of odd numbers in the population is equal to the mean of the sample proportions of even numbers.
OD. The proportion of even numbers in the population is equal to the mean of the sample proportions of odd numbers.
Choose the comect answer below.
OA The sample proportions do not target the proportion of even numbers in the population, so sample proportions do not make good estimators of the population proportion.
B. The sample proportions target the proportion of even numbers in the population, so sample proportions make good estimators of the population proportion
OC. The sample proportions target the proportion of even numbers in the population, so sample proportions do not make good estimators of the population proportion.
OD. The sample proportions do not target the proportion of even numbers in the population, so sample proportions make good estimators of the population proportion
