Having calculated a 95% confidence interval for a single population mean we may state that the odds are 95/100 that the:

Population mean falls in the interval

Sample mean is the same as the population mean

Population mean equals 95

Obtained interval contains the population mean

When calculating Cohen's d as a measure of effect size, the difference between two means is:

	Placed in the denominator
	Divided by N 1
	Divided by the population standard deviation
	Divided by N
