Suppose the height (in inches) of adult males in the U. S.A are normally distributed with a mean of 72 inches and a standard deviation of 2 inches. Find the percent of men who are less than 68 inches tall.

Find the percent of men who are between 70 and 72 inches tall.

Find the percent of men who are at least 76 inches tall.

Find the probability that a randomly selected man is more than 72 inches tall.

Find the probability that a randomly selected man is between 68 and 76 inches tall.

Find the probability that a randomly selected man is less than 76 inches tall.

Between what 2 heights 68% of data fall?

How many standard deviations below the mean is the height of 70 inches?

In a test for esp (extrasensory perception), the experimenter looks at cards that are hidden from the subject. each card contains either a star, a circle, a wave, a cross or a square.(five shapes) as the experimenter looks at each of 20 cards in turn, the subject names the shape on the card. when the esp study described above discovers a subject whose performance appears to be better than guessing, the study continues at greater length. the experimenter looks at many cards bearing one of five shapes (star, square, circle, wave, and cross) in an order determined by random numbers. the subject cannot see the experimenter as he looks at each card in turn, in order to avoid any possible nonverbal clues. the answers of a subject who does not have esp should be independent observations, each with probability 1/5 of success. we record 1000 attempts. which of the following assumptions must be met in order to solve this problem? it's reasonable to assume normality 0.8(1000), 0.2(1000)%30 approximately normal 0.8(1000), 0.2(1000)% 10 approximately normal srs it is reasonable to assume the total number of cards is over 10,000 it is reasonable to assume the total number of cards is over 1000
