Suppose we are interested in carrying out the following test:
H:p = 23
H, :μ ≠ 23
A sample of size 12 was used to make a conclusion about this test. The statistician analyzing this sample points out that the sample is skewed right.
What is the test statistic assuming the sample mean and sample standard deviation are 25 and 29, respectively.
O. We need the population standard deviation to carry out this test.
O. t = 25-23/ (29 /√T2)
O. Since our sample is skewed with a sample size less than 30, we cannot use the typical one population mean t-test.
