Suppose the heights of kindergarten children can be described by a Normal model with a mean of 38.2 inches and standard deviation of 1.8 inches. a) What proportion of kindergarten kids should the company expect to be less than 3 feet tall (36 inches)? (three decimal places) b) What percent of kindergarteners are expected to be between 36 inches and 42 inches tall? % (round to one decimal place) c) At least how tall are the biggest 10% of kindergarteners? (to the nearest half-inch) d) Find the z-score for a 36 inch kindergartner. (round to two decimal places)
