Web1 day ago · Expert Answer. Transcribed image text: 5. [3] Use the price-demand equation to find the values of p for which demand is elastic and the values for which demand is inelastic. Assume that price and demand are both positive. x = f (p) = 3380−5p2 The values of p for which demand is elastic are (Use interval notation) The values of p for which ... WebNov 10, 2024 · For our results, we’ll use P(T<=t) two-tail, which is the p-value for the two-tailed form of the t-test. Because our p-value (0.000336) is less than the standard significance level of 0.05, we can reject the null hypothesis. Our sample data support the hypothesis that the population means are different. Specifically, Method B’s mean is ...
