      Since the test value does not fall within the critical region, we don’t reject the null hypothesis. Therefore, there is not enough evidence to support the claim that the average production of peanuts in the state of ... P-value is 2(0. 0446) = 0.0892. Is 0.0892 < 0.05? No.

      USING STATCRUNCH TO CONSTRUCT CONFIDENCE INTERVALS and CALCULATE SAMPLE SIZE Using Statrunch for confidence intervals (I’s) is super easy. As you can see in the assignments, I cover 9.2 before 9.1 because I feel processes involving means are more intuitive. If at any time with any of these processes you’re given data
