Relax! A recent survey asked 1678 people how many hours per day they were able to relax. The results are presented in the following table. Number of Hours Frequency 0 112 1 185 2 337 3 254 4 318 5 230 6 150 7 30 8 62 Total 1678 Consider these 1678 people to be a population. Let X be the number of hours of relaxation for a person sampled at random from this population. (a) Compute the mean ux. Round the answer to two decimal places. (b) Compute the standard deviation ox. Round the answer to three decimal places.

Resting Pulse: earlier this semester we determined our resting pulse. Seventy-nine individuals participated in this data collection. The mean heart rate for all individuals was 65.34 beats per minute. A random sample of 30 heart rates having a mean of 64.97 beats per minute is presented here. Build a frequency table of these data containing six (6) classes with the lower llimit of the second class at 54 beats per minute. Build a chart appropriate for the presentation of these data.
