According to the Centers for Disease Control and Prevention, 33.5% of U.S. adults have high LDL, or "bad" cholesterol. Suppose we sample 240 adults, out of which 81 have high LDL. Based on our sample, what is our estimate for the population proportion of adults with high What is the standard error for our estimate? Using your answers for parts a and b, construct a 95% confidence interval to estimate the population proportion. Can we conclude that the percentage of those that have high LDL is higher than 33.5%? d. Test the CDC's claim that the percentage of those that have high LDL is higher than 33.5% at the a = 0.05 level. Report your p-value and conclusion. a. b. C. LDL?
