Complete question :
Find the standardized test statistic t for a sample with n = 15, x = 10, s = 0.8, H0: μ = 10.5. Round your answer to three decimal places.
Answer:
−2.420614
Step-by-step explanation:
Given that:
Given that:
n = 10
s = 0.8
X = 15
μ = 15.9
Using the relation :
(x - μ) / (s/√n)
(10 - 10.5) / (0.8/√15)
-0.9 / 0.2065591
= −2.420614
Hence, the standardized test statistic = −2.420614
