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

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

The average age of cars owned by residents of a small city is 6 years with a standard deviation of 2.2 years but the distribution is quite skewed. A simple random sample of 400 cars is to be selected, and the sample mean age x bar of these cars is to be computed. We know the random variable x bar has approximately a normal distributuion because of a. the law of large numbers b. the central limit theorem c. simpson's...

. 21 - Calculate the sample mean, the standard deviation of the sample mean, and determine its distribution for varying cases where n is small or large and the population is or is not, normally distributed. Household incomes are right-skewed, because most households earn under $150,000 per year, but a minority earn much, much more. Suppose you wanted to determine what the average household income is in central Illinois. In order to do this, you take a simple random sample...
