Two Means - Unknown, Unequal Variance
10. Hypothesis Testing for Two Samples / Two Means - Unknown, Unequal Variance / Problem 5
Problem 5

The mean SAT Math score for a sample of 100100 students is 540540, with a population standard deviation of 6060. The mean SAT Writing score for a sample of 130130 students is 555555, with a population standard deviation of 5858. At α=0.05\alpha=0.05, can you support the claim that SAT Writing scores are higher than SAT Math scores?
