A random sample of the price (in $) of a hamburger at 37 restaurants in ACME City found: x = $9.83, s = $1.2. Build a 95% Cl for the population mean price of a hamburger in ACME City. Round all intermediate calculations to two decimals, then construct the Cl and enter like this: (min,max). Do not include the $ sign. Note: if you use a built-in CI command on a calculator/computer, you might get marked wrong due to rounding. Use the formulas given in the text/notes. a. Since n 2 30, O We use s, not o O We use a Z-interval O We use a T-interval O It is not important that hamburger prices be normally distributed b. The Cl is:
