Number 1: The serum cholesterol levels of a population of 12 to 14 year olds follow a normaldistribution with mean 162mg/dl and standard deviation 28 mg/dl.a) What percentage of 12 to 14 years olds have serum cholesterol between 152 and 172mg/dl?b) Suppose we are to choose at random from the population of large number of groups ofnine 12 to 14 years old each. In what percentage of the groups the group mean cholesterolvalue would be between 152 and 172 mg/dl?c) If Y represents the mean cholesterol value of a random sample of nine 12 to 14 year fromthe population, what is Pr(152 < Ỹ < 172)?

Given,sample size(n)=9mean(μ)=162standard deviation(σ)=28
