Question 324272: can someone tell me if i solved this correctly? a manager of a baseball stadium wished to construct a 90% confidence interval for the average age of all baseball fans. in a random sample of 40 fans, the meanage ws 32.5 years with a standard deviation of 2.3 years. construct the interval. why would the manager find this information useful?
margin of erro=.60
32.5+.60=32
32.5-.60=33
so the average age of baseball fans is between 32 and 33 yrs old
