Suppose you have a population of women aged 20-29 with a population mean serum cholesterol of 183 and a population standard deviation serum cholesterol of 37.
a) Identify the sampling distribution of the sample mean for a sample of size 100.
b) Did you apply the central limit theorem? Explain.
Find the probability that the sample mean serum cholesterol for a sample of 100 from the
population is:
c) less than 189
d) greater than 189
e) between 180 and 189

Two language majors, anna and megan, took exams in two languages. anna scored 85 on both exams. megan scored 74 on the first exam and 85 on the second exam. overall, student scores on the first exam had a mean of 82 and a standard deviation of 4, and the second exam scores had a mean of 71 and a standard deviation of 13. a) to qualify for language honors, a major must maintain at least an 85 average across all language courses taken. so far, which of anna and megan qualify? b) which student's overall performance was better?
