The physical fitness of an athlete is often measured by how much oxygen the athlete takes in (which is recorded in milliliters per kilogram, ml/kg). The mean maximum oxygen uptake for elite athletes has been found to be 69 with a standard deviation of 7.5. Assume that the distribution is approximately normal.Find the probability that an elite athlete has a maximum oxygen uptake of at least 88.5 ml/kg. Find the probability that an elite athlete has a maximum oxygen uptake of at most 48.75 ml/kg. Find the probability that an elite athlete has a maximum oxygen uptake of 48.75 ml/kg.
Assume that females have pulse rates that are normally distributed with a mean of μ = 75.0 beats per minute and a standard deviation of o= 12.5 beats per minute. Complete parts (a) through (c) below. a. If 1 adult female is randomly selected, find the probability that her pulse rate is less than 82 beats per minute. The probability is (Round to four decimal places as needed.) b. If 25 adult females are randomly selected, find the probability that they have pulse rates with a mean less than 82 beats per minute. The probability is (Round to four decimal places as needed.) c. Why can the normal distribution be used in part (b), even though the sample size does not exceed 30? A. Since the distribution is of individuals, not sample means, the distribution is a normal distribution for any sample size. B. Since the distribution is of sample means, not individuals, the distribution is a normal distribution for any sample size. C. Since the mean pulse rate exceeds 30, the distribution of sample…
Assume that females have pulse rates that are normally distributed with a mean of u= 73.0 beats per minute and a standard deviation of o = 12.5 beats per minute. Complete parts (a) through (c) below. a. If 1 adult female is randomly selected, find the probability that her pulse rate is between 67 beats per minute and 79 beats per minute. The probability isN (Round to four decimal places as needed.) b. If 4 adult females are randomly selected, find the probability that they have pulse rates with mean between 67 beats per minute and 79 beats per minute. The probability is (Round to four decimal places as needed.) c. Why can the normal distribution be used in part (b), even though the sample size does not exceed 30? O A. Since the original population has a normal distribution, the distribution of sample means is a normal distribution for any sample size. O B. Since the distribution is of sample means, not individuals, the distribution is a normal distribution for any sample size. O C.…
