The pulse rates of 200 college men are normally distributed with a mean of 72 and standard deviation 6. Using the empirical rule, find (a) the percentage of college men whose pulse rates are between 66 and 84. Do not write the percent sign. (b) the percentage of college men whose pulse rates are at most 60. Do not write the percent sign. (c) the number of college men whose pulse rates are at least 78. Do not give answer...

Assume that an adult female is randomly selected. Suppose females have pulse rates that are normally distributed with a mean of 77.0 beats per minute and a standard deviation of 12.5 beats per minute. Find the probability of a pulse rate between 63 beats per minute and 71 beats per minute. (Hint: Draw a graph.) The probability is . (Round to four decimal places as needed.)

3/ 12 pts Question 5 Pulse Rates of Men. A simple random sample of 40 men results in a standard deviation of 10.3 beats per minute (based on the data set provided). The normal range of pulse rates of adults is typically given as 60 to 100 beats per minute. If the range rule of thumb is applied to that normal range, the result is a standard deviation of 10 beats per minute. Use the sample results with...

A simple random sample of 50 men from a normally distributed population results in a standard deviation of 10.8 beats per minute. The normal range of pulse rates of adults is typically given as 60 to 100 beats per minute. If the range rule of thumb is applied to that normal range, the result is a standard deviation of 10 beats per minute. Use the sample results with a 0.05 significance level to test the claim that pulse rates of...

Assume that an adult female is randomly selected. Suppose females have pulse rates that are normally distributed with a mean of 74.074.0 beats per minute and a standard deviation of 11.511.5 beats per minute. Find Upper P 90P90 , which is the pulse rate separating the bottom 9090 % from the top 1010 %. (Hint: Draw a graph.)

A simple random sample of 46 men from a normally distributed population results in a standard deviation of 10.5 beats per minute. The normal range of pulse rates of adults is typically given as 60 to 100 beats per minute. If the range rule of thumb is applied to that normal? range, the result is a standard deviation of 10 beats per minute. Use the sample results with a 0.05 significance level to test the claim that pulse rates of...
