A little girl named Sami is normally not allowed to have soda. But for her 7th birthday, she is allowed to have as much as she wants. The restaurant serves drinks in pint glasses (160z), but Sami won't always consume a full pint of soda due to ice and refills. On her birthday, in one sitting she consumed the following quantities of a pint (16 oz) of soda. 15.4 oz, 15.0 oz, 15.1 oz, 15.3 oz, 15.2 oz Suppose that the amount of soda in a pint glass follows a Normal(u, o2) distribution and that Sami's five drinks represent a random sample. (a) Construct and interpret a 95% confidence interval for o2. (b) Construct and interpret a 95% confidence interval for o. (c) Find a 99% confidence upper bound for o
