WebThe figure below is the graph of a derivative f'. Give the x-values of the critical points of f. At which critical points does f have local maxima, local minima or neither? Enter the critical points in increasing order. Round your answers to the nearest integers. WebBecause our alpha falls between the z-values of -1.64 and -1.65, you can interpolate to find a more precise critical value between them. Instead, I chose the marginally more conservative critical z-value of -1.65. If the one-tailed z-test is for the left tail, use -1.65 for the critical value. WebLeft-tail critical value: 1 – (0.05 / 2) = 0.975. In the chi-square table below, I highlight these two results. The chi-square table shows that our lower critical value is 0.831 and the upper critical value is 12.833. Consequently, our results are statistically significant if the χ 2 test statistic when ≤ 0.831 or ≥ 12.833. evoshield mlb catcher\u0027s thumb guard
