Question

Please help with questions A-D. C. What is the standard Deviation D. If the sample were increased to 80, how would your answer to parts a-c change? For part A the shape of the distribution would (be normally distributed, skewed right, or skewed left )? For part B the mean of the sampling distribution would (remain as or change to)? For part C the standard deviation of the sampling would (remain as or change to)?

According to a recent poll, 29% of adults in a certain area
have high levels of cholesterol. They report that such
elevated levels "could be financially devastating to the
regions healthcare system" and are a major concern to
health insurance providers. According to recent studies,
cholesterol levels in healthy adults from the area average
about 210 mg/dL, with a standard deviation of about 30
mg/dL, and are roughly Normally distributed. Assume
that the standard deviation of the recent studies is
accurate enough to be used as the population standard
deviation. If the cholesterol levels of a sample of 40
healthy adults from the region is taken, answer arts

Definition Definition Measure of central tendency that is the average of a given data set. The mean value is evaluated as the quotient of the sum of all observations by the sample size. The mean, in contrast to a median, is affected by extreme values. Very large or very small values can distract the mean from the center of the data. Arithmetic mean: The most common type of mean is the arithmetic mean. It is evaluated using the formula: μ = 1 N ∑ i = 1 N x i Other types of means are the geometric mean, logarithmic mean, and harmonic mean. Geometric mean: The nth root of the product of n observations from a data set is defined as the geometric mean of the set: G = x 1 x 2 ... x n n Logarithmic mean: The difference of the natural logarithms of the two numbers, divided by the difference between the numbers is the logarithmic mean of the two numbers. The logarithmic mean is used particularly in heat transfer and mass transfer. ln x 2 − ln x 1 x 2 − x 1 Harmonic mean: The inverse of the arithmetic mean of the inverses of all the numbers in a data set is the harmonic mean of the data. 1 1 x 1 + 1 x 2 + ...
