When testing the hypothesis H₀: μ = 100 with n = 100 and σ² = 100, we find that the sample mean is 97. The test statistic is: A)-3.000 B)-10.00 C)-0.300 D)-0.030

Question

Quizplus · Accepted Answer

To calculate the test statistic, we use the formula:
test statistic = (sample mean - hypothesized mean) / (standard deviation / square root of sample size)
Plugging in the values, we get:
test statistic = (97 - 100) / (100 / √100) = -3.00
Therefore, the correct answer is A.
