Summary statistics are given for independent simple random s

Summary statistics are given for independent simple random samples from two populations. 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 = 566.9, s1 = 31.2, n1 = 37, 2 = 480.2, s2 = 33.5, n2 = 42

Solution

Reasonable as the two random samples have similar size of samples

and the standard deviation is also more or less similar
