Find the standardized test statistic t for a sample with n = 12, x = 14.1, s = 1.3, and α = 0.05 if H0: μ ≥ 15. Round your answer to three decimal places.
Solution:
This is a left tailed test,
The test statistics,
t =(
-
)/ (s /
n)
= ( 14.1 - 15 ) / ( 1.3 /
12 )
= -2.398
P-value = 0.0177
The p-value is p = 0.0177 > 0.05, it is concluded that the null hypothesis is fail to rejected.

You wish to test the claim that μ ≠ 22 at a level of significance of α = 0.05 and are given sample statistics n = 35, x = 21.1, and s = 2.7. Compute the value of the standardized test statistic. Round your answer to two decimal places. a)Ho:___Ha:___
The one-sample t statistic from a sample of n = 21 observations for the two-sided test of H0: μ = 60, Ha: μ ≠ 60 has the value t = –1.98. Based on this information: we would reject the null hypothesis at α = 0.05. All of the answers are correct. 0.025 < P-value < 0.05. we would reject the null hypothesis at α = 0.10
