Suppose that you wanted to estimate the average amount of time at a school student spends per day exercising. you decide to do this by taking a random sample of students from your school. You will calculate the mean time spent exercising for your sample. You will then use your sample me in as an estimate of the population mean. When you are using a sample statistic to estimate a population characteristic, do you want to sampling variability of the sample statistic to be large or small? Explain why.

Our star pitcher, foster enlight, can throw a pitch so fast that it gets to the catcher’s mitt before it leaves foster’s fingers! if the team wins a game then the probability that foster was pitching is 0.8 but only if foster had at least one day’s rest since his last pitching assignment. if foster does not have a day off and the team still wins, the probability that foster was pitching drops by half of what it was on the previous day. if the team wins three games in succession from the toronto tachyons and foster pitched in game #2, what is the probability that he pitched in one or more of the other games? (assume that foster did not pitch on the day before the first game of this three game series.)
