Scooter's Tavern boasts that they have the "Coldest Beers in Town". A curious citizen tested a random sample of 39 beers and found a mean temperature of 34.9, with a standard deviation of 0.84. We are going to construct a 93% confidence interval for the mean temperature of all beers in the tavern. Round all answers to 3 decimal places
What is the point estimate for our confidence interval?
For the critical value, should we use the Z-statistic or the T-statistic?
Since we know the population standard deviation, we should use the Z-statistic.
Since we only know the sample standard deviation, we should use the Z-statistic.
Since we know the population standard deviation, we should use the T-statistic.
Since we only know the sample standard deviation, we should use the T-statistic.
What is the margin of error?
