Question: Problem 2: A certain group of tests subjects had pulse rates with a mean of 70.1 beats per minute and a standard deviation of 11.8

Problem 2: A certain group of tests subjects had pulse rates with a mean of 70.1 beats per minute and a standard deviation of 11.8 beats per minute. Apply the Range Rule of Thumb to find rough estimates of the minimum and maximum usual sample values: a)Minimum "usual" value = ___________________

  1. Maximum "usual" value = ____________________

  1. Would it be unusual for one of the test subjects to have a pulse rate of 73.7 beats per minute? _________________

  1. Empirical Rule:For data sets having a distribution that is approximately NORMAL.

68% lie within Standard deviation of the mean

95% Lie within Standard deviation of the mean

99.7% Lie within Standard deviation of the mean

Problem 3: Heights of men on a baseball team have a bell shaped distribution with a mean of 175 cm and a standard deviation of 8 cm. Using the empirical rule, what is the approximate percentage of the men between 151 cm and 199 cm? ________________________________________________
