Suppose the heights of 18-year-old men are approximately normally distributed, with mean 68 inches and standard deviation 5 inches. (a) What is the probability that an 18-year-old man selected at random is between 67 and 69 inches tall? (Round your answer to four decimal places.) (b) If a random sample of thirteen 18-year-old men is selected, what is the probability that the mean height x is between 67 and 69 inches? (Round your answer to four decimal places.)
Suppose the heights of 18-year-old men are approximately normally distributed, with mean 69 inches and standard deviation 1 inch. If a random sample of thirty 18-year-old men is selected, what is the probability that the mean height x is between 68 and 70 inches? (Round your answer to four decimal places.)
Suppose the heights of 18-year-old men are approximately normally distributed, with mean 68 inches and standard deviation 3 inches. (a) Find the percentage of 18 year old men with height between 67 and 69 inches. (b) Find the percentage of 18 year old men taller than 6 foot. (c) if a random sample of nine 18 year old men is selected, what is the probability that their mean height is between 68 and 72 inches? (d) if a random sample...
Heights of men are normally distributed with a mean of 69.0 inches and a standard deviation of 2.8 inches. What is the probability that a randomly selected group of 16 men have a mean height greater than 71 inches.
Assume that the height of men are normally distributed with a mean
of 69.8 inches and a standard deviation deviation of 3.5 inches. If
100 men are randomly selected, find thr probability that they have
a mean height greater than 69 inches.
Asume that the heights of men are normally distributed with a mean of 69.8 inches and a standard deviation of 3.5 inches of 100 men wa randomly selected in the probability that they have a meaning greater than...
Assume that the heights of men are normally distributed with a mean of 68.1 inches and a standard deviation of 2.8 inches. If 64 men are randomly selected, find the probability that they have a mean height greater than 69.1 inches
Suppose the heights of males on campus are normally distributed with a mean of 69 inches and standard deviation of 2.5 inches. You plan to choose a random sample of 14 males from the studer directory a. What is the probability the mean height for your sample will be greater than 70.5 inches? b. The sample size you used was fairly small. Does this affect the validity of the probability you calculated in (a)? Explain fully!
Suppose the heights of 18-year-old men are approximately normally distributed, with mean 66 inches and standard deviation 1 inches. (a) What is the probability that an 18-year-old man selected at random is between 65 and 67 inches tall? (Round your answer to four decimal places.) (b) If a random sample of twenty 18-year-old men is selected, what is the probability that the mean height x is between 65 and 67 inches? (Round your answer to four decimal places.)
Assume that the heights of men are normally distributed with a mean of 690 inches and a standard deviation of 28 inches Find the probability that a randomly selected man has a high greater than 700 inches O A 0.0058 OB. 0.9942 O 06395 OD. .3605
If the heights of women are normally distributed with a mean of 65.0 inches and a standard deviation of 2.5 inches and the heights of men are normally distributed with a mean of 69.0 inches and a standard deviation of 2.8 inches, At 71 inches what is the probability for the height of a person of your gender to be within 3 inches of your height (between “your height – 3 inches” and “your height + 3 inches”)?
