One season, the average little league baseball game averaged 2 hours and 46 minutes (166 minutes) to complete. Assume the length of games follows the normal distribution with a standard deviation of 10 minutes. What is the probability that a randomly selected game will be completed in more than 180 minutes? (Round to four decimal places as needed.)

A recent survey revealed that an American's Christmas spending averaged $830. Use this as the population mean American's Christmas spending. Suppose Americans' Christmas spending is normally distributed with a standard deviation of $220. A random sample of size 100 is selected from the population of American consumers. What is the probability that the sample mean spending is no more than $840?

George is studying the average time, per game, that people under 25 watch baseball games. He conducted a study with 16 college age students that found a M = 55 minutes watching with a s = 8. He wants to know if the people under 25 spend significantly less time watching baseball than the average fan. He can’t find any data on the population mean but assumes µ = 60 minutes. Answer the following questions if George used p =...
