Pulse rates of women are normally distributed with a mean of 77.5 beats per minute and a standard deviation of 11.6 beats per minute. Answer the following questions. What are the values of the mean and standard deviation after converting all pulse rates of women to z scores using z = (x - mu )/sigma ? mu = sigma = The original pulse rates are measure with units of "beats per minute". What are the units of the corresponding z...

> Women’s pulse rates are normally distributed with a mean of 68.5 beats per minute and a standard deviation of 10.9 beats per minute. What is the z-score for a woman having a pulse rate of 65 beats per minute?
In a particular city, pulse rates are normally distributed, with a mean of 70.4 beats per minute and a standard deviation of 9.9 beats per minute. A researcher is doing a study that requires volunteers whose pulse rates are in the highest 30%. What is the pulse rate that separates the highest 30% from the rest? Include the correct units!
A simple random sample of pulse rates of 50 women from a normally distributed population results in a standard deviation of 12.5 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 0.10 significance level to test the claim that...
Suppose that pulse rates among healthy adults are normally distributed with a mean of 79 beats/minute and a standard deviation of 8 beats/minute. What proportion of healthy adults have pulse rates that are more than 81 beats/minute? Round your answer to at least four decimal places.
Suppose that pulse rates among healthy adults are normally distributed with a mean 79 of beats/minute and a standard deviation of 10 beats/minute. What proportion of healthy adults have pulse rates that are less than 92 beats/minute? Round your answer to at least four decimal places
Assume that females have pulse rates that are normally distributed with a mean of u=76.0 beats per minute and a standard deviation of 0=12.5 beats per minute. A) If 1 adult female is randomly selected, find the probability that her pulse rate is between 70 beats per minute and 82 beats per minute. the probability is___ B) If 16 adult females are randomly selected, find the probability that they have pulse rates with a mean between 70 beats per minute...
