The LDL cholesterol level of all men aged 20 to 34 follows the Normal distribution with mean μ=120μ=120 milligrams per deciliter and the standard deviation is σ=30σ=30 milligrams per deciliter. If you choose an SRS of 25 men from this population, what is the sampling distribution of mean cholesterol level of the 25 selected men. Select one: a. x¯∼N(120,1.2)x¯∼N(120,1.2) b. Couldn't decide c. x¯∼N(120,30)x¯∼N(120,30) d. x¯∼N(120,6)

Cholesterol levels for a group of women aged 50-59 follow an approximately normal distribution with mean 216.57 milligrams per deciliter (mg/dl). Medical guidelines state that women with cholesterol levels above 240 mg/dl are considered to have high cholesterol and about 29.6% of women fall into this category. 1. What is the Z-score that corresponds to the top 29.6% (or the 70.4-th percentile) of the standard normal distribution? Round your answer to three decimal places. 2. Find the standard deviation of...

The score on a proficiency measure is assumed to follow a normal distribution. A switch to better lighting might change the score. A random sample of 30 people taken during the year before the switch to better light yielded a mean score of 600 and a variance of 400. A different random sample of 30 people after the switch had a mean of 610 and a variance of 441. Important: use a degrees of freedom nu=80 for the t statistic....

The distribution of blood cholesterol level in the population of young men aged 20 to 34 years is close to Normal with standard deviation σ = 45 milligrams per deciliter (mg/dL). You measure the blood cholesterol of 12 cross-country runners. The mean level is x = 172 mg/dL. Assume that σ is the same as in the general population. How large a sample is needed to cut the margin-of-error in half for a 90% confidence interval of the mean level...
