Assume the standard deviation from the recent studies is accurate and known. According to recent studies, cholesterol levels in healthy adults from the area average about 209 mg/dL, with a standard deviation of about 35 mg/dL, and are roughly Normally distributed. If the cholesterol levels of a sample of 49 healthy adults from the region is taken, answer parts (a) through (d). (a) What is the probability that the mean cholesterol level of the sample will be no more than 209? P(y5209) = 0.500 (Round to three decimal places as needed.) (b) What is the probability that the mean cholesterol level of the sample will be between 204 and 214? P(204
