Part B. 1. Suppose we have calculated X = 0.5 and s = 1 from a simple random sample of size n = 40 drawn from a population with mean u. Calculate the p value for testing Ho : M = 0 against HA : U > 0, and carry out the test at the 5% significance level. 2. Recalculate the p values for the same test as in question 1 with s = 1 but instead (a) X = 0.4, (b) X = 0.3, (c) X = 0.2, (d) X = 0.1 3. Recalculate the p values where X = 0.5 but now (a) s = 1.5, (b) s = 2, (c) s = 2.5, (d) s = 3
