Use the magnitudes (Richter scale) of the 120 earthquakes listed in the accompanying data table. Use technology to find the range, variance, and standard deviation. If another value, 8.00, is added to those listed in the data set, do the measures of variation change much? 3.272.452.542.432.752.372.192.421.911.432.851.731.992.322.332.704.742.873.382.722.833.423.952.993.873.473.082.942.703.602.842.373.033.232.593.643.242.662.352.432.813.952.522.922.983.412.272.562.933.162.201.151.934.002.542.832.352.311.522.801.951.602.452.332.081.553.201.491.812.551.662.352.452.082.192.752.002.792.392.671.692.881.841.991.862.561.972.183.671.553.162.461.881.502.793.283.822.752.452.712.541.642.183.032.361.481.922.322.651.411.391.802.242.302.481.732.402.442.482.44

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.
