1) A professor to estimate the mean amount of money that college students
spend eating out each week. He take a simple random of students and ask them to report how much they spent eating out last week. What type of confidence interval should he use?
2) If a large number of samples, of size n, are taken from Po (2.9) and approximately
1% of the sample means are greater than 3.41, estimate n
3) Consider samples of size n
= 25 from a population with p = 0.8. Is the sample size large enough so that the sample proportions follow a normal distribution? Yes or No? Justify your answer by showing the conditions test you used to reach your conclusion.
