Suppose X ~ N (2, 4). Between what :i: values does 68.28% of the data lie? H" i" the blanks. Jerome averages 16 points a game with a standard deviation of four points. X ~ N (16,4). Suppose Jerome scores 22 points in a game. The zscore when a: = 22 is 1.5. The range of :i: values is centered at the mean of the distribution (i.e., 2). Enter the exact answers. Enter your answers in increasing order. to the nearest integer. This score tells you that z = 22 is Number standard deviations to the Click to: LISt v of the mean Number 68.28% of the data lie between Number and Number Suppose X has a normal distribution with mean 25 and standard deviation ve.

Round the answer to three decimal places. According to a study done by De Anza students, the height for Asian adult males is normally distributed with an average of 66 inches and a standard deviation of 2.5 inches. Suppose one Asian adult male is randomly chosen. Let X = height of the individual. (a) State the distribution of X. XN N( Number , Number ) (b) Find the probability that the person is between 64 and 69 inches. Select the correct graph for the situation with shading for the region corresponding to the probability. usess Round your new in (our decimal was. a necessary.
