To find the standardized value of x: z = (x - $\bar{x}$)/SD(x) We are given $\bar{x}$ = 5 and S_x = 2, but we need to find SD(x). SD(x) = √(S_x/N) where N is the sample size. Since N is not specified in the problem, we cannot calculate the exact value of SD(x) but we can find an estimate. Let's assume that N = 10 (for example) to find an estimate of SD(x). SD(x) = √(2/10) = 0.45 (approx.) Now we can calculate the standardized value of x: z = (7 - 5)/0.45 = 4.44 Therefore, the answer is A) 1.
