Researchers at a university took a simple random sample of 124 healthy individuals and found these results: The distribution is approximately normal The sample mean is 98.24°F The standard deviation is 0.6°F We want to determine whether these sample results differ from 98.60°F by a significant amount. One way to make that determination is to study the behavior of samples drawn from a population with a mean of 98.60. In other words, we’re going to assume the population mean really is 98.60. We’re going to see what normal sample means would look like if the population mean really was 98.60. Generate 25 samples of 124 individuals from a normally distributed population with a mean of 98.60 and a standard deviation of 0.6. This means each column should have 124 entries and you should be using columns A - Y. If you need a refresher on generating a random sample from a normally distributed population, review the Technology Corner from Module 2. After generating the random samples, you should copy the numbers and then "Paste Values" so the random numbers don't keep regenerating. Save your Excel file and attach it here: Keep in mind that your Excel file is what samples would look like if the population mean really is 98.60. What is the lowest sample mean you obtained? Note: While there are no points associated with the attachment or the lowest mean, points will be deducted for not completing this portion or doing it incorrectly. These should be used to help you understand the remainder of the problem. Based solely on the simulations, would it be reasonable to obtain a sample mean of 98.24? yes no If we assume the population mean is 98.60 and the standard deviation is 0.6, what is the probability of a single person having a temperature of 98.24 or less? (Round to four decimal places.This should be the theoretical probability that is calculated, NOT the empirical probability from the simulation.) If we assume the population mean is 98.60 and the standard deviation is 0.6, what is the probability of obtaining a sample mean of 98.24 or less from a sample of 124 individuals? (Round to six (6) decimal places.This should be the theoretical probability that is calculated, NOT the empirical probability from the simulation.) What can we say about the assumption that the population mean is 98.60? Explain your answer completely. Keep in mind: The simulation you completed was under the assumption that the population mean is 98.60. The calculations you completed in the last two portions were assuming the population mean is 98.60. The sample that produced a mean of 98.24 degrees was the actual, real data.
