Suppose that we are to conduct the following hypothesis test: H0: μ=1020 H1: μ>1020 Suppose that you also know that σ=220, n=95,x¯=1053, and take α=0.05. Draw the sampling distribution, and use it to determine each of the following: A. The value of the standardized test statistic: Note: For the next part, your answer should use interval notation. An answer of the form (−∞,a)(−∞,
