Below are data for n = 20 individuals indicating the resting pulse rate of each person, and whether or not that person regularly exercises.

Exercise and pulse rate data

Person	Resting pulse rate	Regularly exercises
1	72	No
2	62	Yes
3	72	Yes
4	84	No
5	60	Yes
6	63	Yes
7	66	No
8	72	No
9	75	Yes
10	60	Yes
11	62	No
12	84	No
13	76	No
14	60	Yes
15	52	Yes
16	60	No
17	64	Yes
18	74	Yes
19	68	Yes
20	64	Yes

Assuming this is a random sample from a larger population, carry out a hypothesis test to determine whether the mean pulse rate differs between those who do regularly exercise and those who don't regularly exercise. Use alpha = .05, and show all four steps.

Resting Pulse Rate The mean resting pulse rate for men is 72 beats per minute. A simple random sample of men who regularly work out at Planet Fitness 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. Follow the 5-step example I posted (and the setup in question...

The resting pulse rate of a simple random sample of 9 women was recorded yielding a mean resting pulse rate of 76 beats per minute with standard deviation 5. Use this information for this question and the next one. The p-value of a statistical test where the alternative hypothesis is that the mean resting pulse rate is greater than 72 is: (a) Between 0 and 0.01 (b) Between 0.01 and 0.025 (c) Between 0.025 and 0.05 (d) Between 0.05 and...

A first year statistics class took part in a simple experiment. Each person took their pulse rate. They then flipped a coin and, if it came up tails, they ran in place for one minute. Everyone then took their pulse a second time. Of the 92 students in the class, 32 ran in place. In repetitions of this experiment, the number that run in place should have a binomial distribution with n = 92 trials and probability of success p...
