SOLUTION: In a test of hypotheses H0: µ = 212 versus H1: µ > 212, the rejection region is the interval [1.895, ∞), the value of the sample mean computed from a sample of size 10 is 225

Question 929509: In a test of hypotheses H0: µ = 212 versus H1: µ > 212, the rejection region is the interval [1.895, ∞), the value of the sample mean computed from a sample of size 10 is 225, and the value of the test statistic is t = 2.44. The correct decision and justification are:





A Do not reject because 2.44 is greater than 1.895

B Reject because 225 is larger than 212

C Reject because 2.44 falls in the rejection region

D Do not reject because 2.44 falls in the acceptance region

E Do not reject because the sample size of 10 is too small

2.44 > 1.895
C. Reject because 2.44 falls in the rejection region [1.895, ∞)
