The Statistics Games are played by a large number of teams across the county. Teams raise money to cover expenses incurred by participating. You want to estimate the mean amount of money raised by teams. You take a random sample of 36 teams and find a mean of $375 and a standard deviation of $32. Have the conditions for inference been met? (ie, can you safely calculate a confidence interval?) A Yes, the sample is random and the sample size is more than 30. B Yes, the population standard deviation is given. C No, the whole population was not given a chance to respond. D No, because the sample standard deviation is given. E No, the sample is not large enough.
