Question

If, in a sample of nequals16 selected from a normal​ population, Upper X overbar equals 60 and Upper S equals 20​, what is your statistical decision if the level of​ significance, alpha​, is 0.01​, the null​ hypothesis, Upper H 0​, is mu equals 50 comma and the alternative​ hypothesis, Upper H 1 comma is mu not equals 50 question mark Click here to view page 1 of the table of the critical values of t. LOADING... Click here to view page 2 of the table of the critical values of t. LOADING... Determine the critical​ value(s). The critical​ value(s) is(are) 0.05 nothing. ​(Round to four decimal places as needed. Use a comma to separate answers as​ needed.)

Answer 1

n = Sample Size = 16

= Sample Mean = 60

s = Sample SD = 20

= Significance level = 0.01

H0: Null Hypothesis: = 50

H1: Alternative Hypothesis: 50

Degrees of Freedom = n - 1 = 16 - 1 = 15

From Table, critical values of t = 2.9467

So,

Answer is:

The critical​ values are:

- 2.9467, 2.9467
