Accоrding tо the Wоrld Heаlth Orgаnizаtion, distribution of height in centimeters for 5-year old girls is normal with the mean height of 109 cm and the standard deviation of 4.5 cm. Let X be the height of one randomly selected 5-year old girl. Thus, X ~ N(109, 4.5). a. Find the z-score for a height of 102 centimeters. Round your answer to 2 decimal places. Is it unusual? Explain. b. Find the z-score for a height of 120 centimeters . Round your answer to 2 decimal places. Is it unusual? Explain. c. What height corresponds to a z-score of 1 in this population? d. Using the empirical rule, we expect about 95 percent of the values in a normal distribution to lie within two standard deviations above or below the mean. What does this mean, in terms of a specific range of values, for this distribution?
