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 that that these sample pulse rates come from a population with a mean less than 72 beats per minute.

Astudent hypothesized that watching sports on television would cause viewers’ pulse rates to increase. she designed an experiment to determine the effect of watching sports on pulse rate. a group of 200 volunteers took their pulse rates and then watched their favorite sports on television. after the games, they immediately took their pulse rates again. the data collected showed that the pulse rates of some people increased, but the pulse rates of an equal number of people did not change. although the hypothesis was not supported by the data, the hypothesis is still valuable because it 1. may lead to further investigation 2. can be changed to fit the data 3. is the opinion of the experimenter 4. is based on beliefs of the volunteers

Question 10suppose that a student is working on a statistic project using data on pulserates collected from a random sample of 100 students from her college. shefinds a 95% confidence interval for mean pulse rate to be (65.5, 71.8). explainhow each of the statement below would indicate an improper interpretation ofthis intervala) i am 95% sure that all students will have pulse rates between 65.6 and71.8 beats per minuteb) i am 95% sure that the mean pulse rate for this sample of students will fallbetween 65.5 and 71.8 beats per minutec) i am 95% sure that the confidence interval for the average pulse rate of allstudents at this college goes from 65.5 to 71.8 beats per minuted) i am sure that 95% of all students at this college will have pulse ratesbetween 65.5 and 71.8 beats per minutee) i am 95% sure that the mean pulse rate for all us college students inbetween 65.5 and 71.8 beats per minutef) of the mean pulse rates for students at this college, 95% will fall between65.5 and 71.8 beats per minuteg) of random samples of this size is taken from students at this college, 95%will have mean pulse rates between 65.5 and 71.8 beats per minute.
