Myles and his family love chocolate. During quarantine they devoured a 50-pack box of 1.69 ounce M&M bags from Costco.

Round the mean and SD to the nearest TENTHS place. a) Is google’s claim accurate? Perform a hypothesis test. b) Create a 95% confidence interval. c) Interpret what 95% confidence means in context.
