health insurance providers According to recent studies, cholesterol levels in healthy adults from the area average about 209 mg/dl, with a standard deviation of about 35 myld, 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 the cholesterol levels of a sample of 44 healthy adults from the region is taken answer parts a
through d
OC. The sampling distribution of the mean is skewed lett
OD. There is not enough information to determine the shape of the sampling distribution
b) What is the mean of the sampling distribution?
-209 mg/d
c) What is the standard deviation?
SD)-528 mg/d (Round to two decimal places as needed)
d) If the sample size were increased to 80. how would your answers to parts ac change?
For part a, the shape of the distribution would also be normally distributed
For part b the mean of the sampling distribution wor
For part c. the standard deviation of the sampling distribution would
would remain a
