Heights of 10 year olds, regardless of gender, closely follow a normal distribution withmean 55 inches and standard deviation 6 inches.(a) If the tallest 8% of the class is considered "very tall", what is the height cutoff for "very tall"?(please round to one decimal place)(b) The height requirement for Batman the Ride at Six Flags Magic Mountain is 56 inches. Whatproportion of 10 year olds cannot go on this ride? In other words, what is probability a random 10 yearold is below 56 inches? Note this question is not a percentile question.(Use three significantfigures.)
