- I’m interested in analyzing the pulse rates from the NSCC
Student dataset.
- Calculate the sample mean of the Pulse Rate variable. Denote answer with proper symbol.
- Calculate the median of the Pulse Rate variable.
- Calculate the sample standard deviation of the Pulse Rate variable. Denote answer with proper symbol.
- Continue consideration of the pulse rates from the NSCC Student
dataset.
- Create a grouped frequency distribution for the Pulse Rate variable. You may choose how many classes you want. Include a “relative frequency” column in your table as well.
- Estimate the mean for that frequency distribution using the methods learned in section.

Table #7.3.7contains pulse rates after running for 1 minute,
collected from females who drink alcohol ("Pulse rates before,"
2013). The mean pulse rate after running for 1 minute of females
who do not drinkis 97 beats per minute. Do the data show that the
mean pulse rate of females who do drink alcohol is higher than the
mean pulse rate of females who do not drink? Test at the 5%
level.

The mean resting pulse rate for men is 72 beats per minute. A
simple random sample of men who regularly work out at Mitch's Gym
is obtained and their resting pulse rates (in beats per minute) are
listed below. Use a 0.05 significance level to test the claim that
these sample pulse rates come from a population with a mean less
than 72 beats per minute. Assume that the standard deviation of the
resting pulse rates of all men who...
