Question

n = 36 Ho: u 220 x = 18 Ha: u < 20 S= 12 If the test is done at a .05 level of significance, the null hypothesis should not b

Answer 1

Answer #1

Correct option "Not be rejected"

Critical value: tarit= ta/21df = t0.05/2,35 = -1.69 P-value = p (t>|-11) = 0.1621 Fail to reject the null hypothesis. Conclus
