Question
If, in a sample otn 30 selected from a normal population, X-58 and S-8, what is your statistical decision it the level of significance, a, is o 06, the null hypothesis, Ho, is p 50, and the alternative hypothesis, H1 , is 50?

O B The test rejects the nul hypothesis The data prowde suff cent evidence to condude that the mean differs tom -50 The fest rejects the nul hypothesis The data does not provide sufficient evidence to conclude that the mean differs fro m-50 The test does not eyect the null hypothesis The data does not prvide Suficient evdence to condude that the mean diters from n-50 The test does not re ect the null hypothesis The data provde sufficent evidence to conclude that the mean differs from 50 C. O D
Explanation / Answer
Critical value of t = 2.0452
t stat = 5.4772
A. reject null hypothesis. sufficien evidence
