Question 7 0 pts Because cardiac deaths appear to increase after heavy snowfalls, a study was designed to compare cardiac demands of snow shoveling to those using an electric snow thrower. The maximum heart rates (in beats per minute) of ten randomly selected subjects during manual snow shoveling had a mean of 175 beats per minute and a standard deviation of 15. Find and interpret the 99% confidence interval estimate of the population mean heart rate for those who shovel snow
