(a) Determine the population mean pulse. The population mean pulse is approximately beats per minute. (Round to one decimal place as needed.) (b) Determine the sample mean pulse of the following two simple random samples of size 3. Sample 1: (Crystal, Kathy, Megan) Sample 2: (Kevin, Tammy, Clarice) The mean pulse of sample 1 is approximately (Round to one decimal place as needed.) beats per minute. The mean pulse of sample 2, is approximately O beats per minute. (Round to one decimal place as needed.) (c) Determine if the means of samples 1 and 2 overestimate, underestimate, or are equal to the population mean. The mean pulse rate of sample 1 the population mean. The mean pulse rate of sample 2 the population mean.
