Body TemperaturesThe body temperatures (in degrees Fahrenheit) have been recorded for a sample of 130 healthy adults - 65 males and 65 females (Shoemaker, 1996). The sample mean body temperature for males is 98.394 degrees Fahrenheit, and the sample standard deviation for males is 0.743 degrees Fahrenheit. The sample mean body temperature for females is 98.105 degrees Fahrenheit, and the sample standard deviation for females is 0.699 degrees Fahrenheit. a. produce a 95% confidence interval for the population mean body temperature of a healthy male. Round your answers to three decimal places. (___, ___) b. produce a 95% confidence interval for the population mean body temperature of a healthy female. Round your answers to three decimal places. (___, ___) d d. Report the half-width of these two intervals. Round to 3 decimal places. Half width for men: ____ Half width for women: ___
Find the mean, median, standard deviation, and variance of the sample data. Also, from the original data set, find the values of the range and sample size. Identify the modal class (the one with the highest frequency). The statistics should be rounded properly- to the nearest hundredth
