The sample mean was 1?!) beats per minute, and the sample standard deviation was 15 beats per minute. a. Go to Stat>>Tests and choose T-interval because we do not know the population standard deviation In. Find a sum; confidence interval for the true population mean for maximum heart rate. You can use the calculator. Theconfidenceintervalist 161.3 , 113.? }. c. Based on the interval you got, what is the error bound for the population mean? Round to the nearest whole number. |:| d. If you want to create a wider confidence interval, you could
