Calculate the upper and lower limit for a 95% confidence interval about this mean.

a family needs a new car, but isn't sure they can fit the payment into their budget. a sample of 36 months of grocery bills yields a mean of $94 with a standard deviation of $10. if the upper limit of a 95% confidence level is below $100, the family can afford to buy the car.

standard error = (standard deviation)/(square root of sample size)

upper limit (dollars and cents)

lower limit (dollars and cents)
