Women have pulse rates that are normally distributed with a mean of 77.5 beats per minute and a standard deviation of 11.6 beats per minute. a.) What is the probability that a woman has a pulse rate higher than 87.1 beats per minute? b.) What pulse rate would separate the lowest 60% of women from the top 40%? c.) What is the probability that a group of 18 women has a mean pulse rate between 71 and 82 beats per minute?
Women have pulse rates that are
a.) What is the probability that a woman has a pulse rate higher than 87.1 beats per minute?
b.) What pulse rate would separate the lowest 60% of women from the top 40%?
c.) What is the probability that a group of 18 women has a mean pulse rate between 71 and 82 beats
per minute?
d.) Even though the sample size is less than thirty in part (c) of this question, why can the Central Limit still be applied?
e.) If you are a doctor who is selecting pulse rates as cutoff values for determining whether further tests are needed for patients, which result is more relevant to use, part (b) or part (c)? Why?
