Question
Identify each numerical value by "name" (e.g., mean, variance) and by symbol (e.g., x). Choose 1 of the following:
(a) The mean height of 24 junior high school girls is 4'11".
24 = sample mean = x; 4'11" = sample size = n
24 = sample size = n; 4'11" = sample mean = x
24 = sample variance = s2; 4'11" = sample size = n
24 = population variance = 2; 4'11" population mean =
(b) The standard deviation for IQ scores is 16.
16 = population standard deviation =
16 = sample mean = x
16 = sample variance = s2
16 = sample size = n
(c) The variance among the test scores on last week's exam was 190.
190 = sample variance = s2
190 = population standard deviation =
190 = sample size = n
190 = population mean =
(d) The mean height of all cadets who have ever entered West Point is 69 inches.
69 = sample mean = x
69 = sample size = n
69 = population mean =
69 = population standard deviation =
