Answer #1

Answer :

sample mean

EXPLANATION:

Formula for sample standard deviation (s) is given by:

s=\sqrt{\frac{\sum (x-\bar{x})^{2}}{n-1}},

where \bar{x} is the sample mean.

    (b) Use the defining formula to compute the sample standard deviation s. Recall the defining formula used to compute the sample standard deviation s = (x − x)2 n − 1 where x is a member of the data set, x is the mean, and n is number of data values. Before using the formula, we must determine x and n. There are five values in the data set 1, 2, 5, 7, 9, so n = _______. Calculate the...
