Individuals are often classified as being morbidly obese if they are 100 pounds overweight. Imagine that the population proportion of morbidly obese individuals in the country as a whole is 1.5%. 1. How large does n need to be to use the standard normal distribution for hypothesis testing? 2. You obtain information on 500 individuals from a town and calculate the sample proportion to be 3%. 3. Calculate a 93% confidence interval for sample proportion? 4. Does the confidence interval include the population proportion? 5. What is the probability that the sample proportion is equal to the population proportion?
