67 75

95 97

82 87

73 68

59 63

90 88

72 78

Calculate the paired-samples t statistic for these exam scores.

RESULTS OF PAIRED SAMPLE t- test with 8 SAMPLES

t = -0.20 and p = 0.83 >0.5 that means not significant

Using a two-tailed test and a p level of 0.05, identify the critical t values and make a decision regarding the null hypothesis.

FAIL TO REJECT THE NULL HYPOTHESIS WHICH MEANS THERE IS NO SIGNIFICANT DIFFERENCE BETWEEN THE MEANS OF THE TWO EXAMS.

Assume you instead collected exam scores from 1000 students whose mean difference score and standard deviation were exactly the same as for these 8 students. Using a two-tailed test and a p level of 0.05, identify the critical t values and make a decision regarding the null hypothesis.

REJECT NULL HYPOTHESIS WHICH MEANS THERE IS SIGNIFICANT DIFFERENCE BETWEEN MEANS OF TWO EXAMS.

How did changing the sample size affect the decision regarding the null hypothesis?
