Preliminary data analyses indicate that the variable under consideration is normally distributed on each population. Decide whether use of the pooled t-test and pooled t-interval procedure is reasonable. Explain your answer.1 = 143.9, s1 = 43.2, n1 = 13, 2 = 212.9, s2 = 153.7, n2 = 15

Solution

Although, population follows normal distribution, use of the pooled t-test and pooled t-interval procedure is n\'t reasonable because the sample standard deviations are rear to being equal suggesting that the assumption of equal population standard deviations is n\'t reasonable. Also both sample sizes are small in size

Answer: n\'t Reasonable
