2. A random sample of receipts for individuals eating at the Terrace Restaurant showed the sample mean to be X $10.39 with sample standard deviations = $2.15. (a) Use Chebyshev's Theorem to find the smallest interval centered on the mean in which we can expect at least 88.9% of the data to fall. (b) If our sample is normally distributed, what interval will contain exactly 95% of our data?
