Population and Sample Mean

What is another word for AVERAGE?

Calculate the MEAN:

23, 15, 8, 12, 26, 5, 22, 9

Calculate the MEAN:

How do you find the MEAN?

Consider a population with $$\mu=50$$  and $$\sigma=5$$ is taken. Find the mean of the sampling distribution of the sample mean with a sample size of 30.

The mean and standard deviation of a population are 200 and 20, respectively. Sample size is 25. 
What is the mean of the sampling distribution?

The mean of the sampling distribution is the same as the mean of the population.

The average speed of 1500 vehicles traveling on a stretch of highway one particular day is 67 miles per hour with a standard deviation of 3.5 miles per hour. If 100 vehicles are randomly selected as samples, what would be the mean of the resulting sampling distribution of sample means?

The mean of the sampling distribution for average taxi fare where the sample size is 25 is (a)   .
