Question
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 e=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.) Would it be reasonable to sample this number of students? No. This number of IQ test scores is a fairly large number. OYes. This number of IQ test scores is a fairly small number O Yes. This number of IQ test scores is a fairly large number. O No. This number of IQ test scores is a fairly small number

A data set includes 106 body temperatures of healthy adult humans having a mean of 98.9°F and a standard deviation of 0.62°F. Construct a 99% confidence interval estimate of the mean body temperature of all healthy humans. What does the sample suggest about the use of 98.6°F as the mean body temperature?

Click here to view page 2 of the standard normal distribution table What is the confidence interval estimate of the population mean u? ***** (Round to three decimal places as needed) What does this suggest about the use of 98.6°F as the mean body temperature? OA. This suggests that the mean body temperature is lower than 98.6°F OB. This suggests that the mean body temperature could very possibly be 98.6°F OC. This suggests that the mean body temperature is higher than 98.6°F
