Sample mean (m) = 50 population mean (µ) = µm = 47 sample standard deviation (s) = 4 sample size (n) = 25 based on this information, compute the t statistic for a one-sample t test. (you may need to compute some other values before computing the t statistic itself). when reporting your t statistic, provide at least two decimal places.

t= 3.75

Step-by-step explanation:

Given : Sample mean (M) = 50

Population mean (µ) = µM = 47

Sample standard deviation (s) = 4

Sample size (N) = 25

∵ Population standard deviation is missing , so we apply t-test.

Test statistic formula :

Substitute all the values in the formula , we get

Hence, the t statistic for a one-sample t test : t= 3.75

the 4th choice is the correct one

step-by-step explanation:

d is the correct answer

step-by-step explanation:

x= 8 because 3x = 3 * 8, and 3*8 = 24
