I'm confused on how to work this problem. A sportswriter wished to see if a football filled with helium travels farther, on average, than a football filled with air. To test this, the writer used 18 adult male volunteers. These volunteers were randomly divided into two groups of nine subjects each. Group 1 kicked a football filled with helium to the recommended pressure. Group 2 kicked a football filled with air to the recommended pressure. The mean yardage for Group...

part 1. You want to obtain a sample to estimate how much parents spend on their kids birthday parties. Based on previous study, you believe the population standard deviation is approximately σ=63.5σ=63.5 dollars. You would like to be 95% confident that your estimate is within 1 dollar(s) of average spending on the birthday parties. How many parents do you have to sample? n= part 2. In a survey, 10 people were asked how much they spent on their child's last...
