A simple random sample from a population with a normal distribution of 103 body temperatures has x=98.10°F and s=0.61°F Construct an 80% confidence interval estimate of the standard deviation of body temperature of all healthy humans. Is it safe to conclude that the population standard deviation is less than 2.10°F? Click the icon to view the table of Chi-Square critical values F<<°F (Round to two decimal places as needed) Is it safe to conclude that the population standard deviation is less than 2.10°F? OA This conclusion is not safe because 2 10°F is outside the confidence intervall OB. This conclusion is safe because 2 10°F is in the confidence interval OC. This conclusion is not safe because 2 10°F is in the confidence interval OD. This conclusion is safe because 2. 10°F is outside the confidence interval
