Which of the following is NOT an observation about critical values? Choose the correct answer below. A. The number Zα/2 is a critical value that corresponds to an area of 1 - α/2 to its left. B. A critical value is the number on the borderline separating sample statistics that are likely to occur from those that are unlikely to occur. C. A critical value is the area in the right-tail region of the standard normal curve. D. The number Zα/2 is a critical value that is a z score with the property that it separates an area of x /2 in the right tail of the standard normal distribution. A data set includes 104 body temperatures of healthy adult humans having a mean of 98.7°F and a standard deviation of 0.66°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.³ What is the confidence interval estimate of the population mean μ? °F<μ< °F (Round to three decimal places as needed.) What does this suggest about the use of 98.6°F as the mean body temperature? A. This suggests that the mean body temperature is significantly lower than 98.6°F. B. This suggests that the mean body temperature is significantly higher than 98.6°F. C. This suggests that the mean body temperature could very possibly be 98.6°F.
