A confidence interval is a range of values that, with a known degree of certainty, includes an unknown population characteristic, such as (7)__________________________________.
To understand confidence intervals, you must be aware of three important properties of the sampling distribution of the mean. (a) The mean of the sampling distribution always equals the (8)___________________________. (b) The standard error of the sampling distribution equals the population standard deviation divided by the square root of the (9)________________________. (c) The shape of the sampling distribution approximates a normal distribution if sample size satisfies the (10)__________________________________________.
