Cats live for 14 years on average, with a standard deviation of 2 years. A simple random sample of 78 recently deceased cats is selected, and the sample mean age at death of these cats is computed. We know that the random variable has an approximately Normal distribution because of a. the law of large numbers. b. the fact that probability is the long-run proportion of times an event occurs. c. the 68–95–99.7 rule. d. the central limit theorem

Dogs live for 14 years on average, with a standard deviation of 2 years. A simple random sample of 78 recently deceased dogs is selected, and the sample mean age at death of these dogs is computed. We know the distribution of the sample mean is approximately normal here because of the central limit theorem the fact that dogs normally live approximately significantly longer than average dog the empirical rule the law of large numbers

Thickness measurements of ancient prehistoric Native American
pot shards discovered in a Hopi village are approximately normally
distributed, with a mean of 4.6 millimeters (mm) and a standard
deviation of 1.0 mm. For a randomly found shard, find the following
probabilities. (Round your answers to four decimal places.)
(a) the thickness is less than 3.0 mm
(b) the thickness is more than 7.0 mm
(c) the thickness is between 3.0 mm and 7.0 mm
