1) If n=19, ¯xx¯(x-bar)=33, and s=18, construct a confidence
interval at a 80% confidence level. Assume the data came from a
normally distributed population.

2) You measure 48 backpacks' weights, and find they have a mean
weight of 44 ounces. Assume the population standard deviation is
2.8 ounces. Based on this, construct a 95% confidence interval for
the true population mean backpack weight.

2. In a survey, 11 people were asked how much they spent on
their child's last birthday gift. The results were roughly
bell-shaped with a mean of $50 and standard deviation of $15.
