A government sample survey plans to measure the LDL (bad) cholesterol level of an SRS of men aged 20 to 34.Suppose that in fact the LDL cholesterol level of all men aged 20 to 34 follows the Normal distribution with mean μ = 115 milligrams per deciliter (mg/dL) and standard deviation σ = 25 mg/dL. Use Table A for the following questions, where necessary. (a) Choose an SRS of 100 men from this population. What is the sampling distribution of x? (Use the units of mg/dL.) N(115, 2.5)N(115, 25) N(0.115, 0.025)N(115, 0.25)N(1.15, 0.25) What is the probability that x takes a value between 113 and 117 mg/dL? This is the probability that x estimates μ within ±2 mg/dL. (Round your answer to three decimal places.)

Question
A government sample survey plans to measure the LDL (bad) cholesterol level of an SRS of men aged 20 to 34.
Suppose that in fact the LDL cholesterol level of all men aged 20 to 34 follows the
μ = 115
milligrams per deciliter (mg/dL) and standard deviation
σ = 25 mg/dL.
Use Table A for the following questions, where necessary.
(a) Choose an SRS of 100 men from this population. What is the sampling distribution of x? (Use the units of mg/dL.)
What is theprobability that x takes a value between 113 and 117 mg/dL? This is the probability that x estimates μ within ±2 mg/dL. (Round your answer to three decimal places.)
