The population of incomes in a particular community is thought to be highly right-skewed with a mean equal to 36,789 and a standard deviation equal to 2,490.
 
  Based on this, if a sample of size n = 36 is selected, the sampling distribution would have a mean equal to the population mean, but the standard deviation of the sampling distribution will be one-sixth of the population standard deviation. Indicate whether the statement is true or false

Question 2

In a two-tailed hypothesis test involving two population variances, if the null hypothesis is true then the F-test statistic should be approximately equal to 1.0.
 
  Indicate whether the statement is true or false
