WebSince the p-value of 0.9805 is greater than a significance level alpha of 0.05, the result of the test is not significant, and we failed to reject the null hypothesis stating that the mean depression score before treatment is less than or equal to the mean depression score after treatment, t 9 = -2.414, p > 0.05. WebWe can use the Standard Normal Cumulative Probability Table to find the z-scores given the probability as we did before. Area to the left of z-scores = 0.6000. The closest value in the table is 0.5987. The z-score corresponding to 0.5987 is 0.25. Thus, the 60th percentile is z …

The Uniform Distribution – Introductory Statistics
WebThe probability will be shown in the curve as 0.556 d. The shaded area for an area of 90% is shown below. Statkey commands: Click Normal in Theoretical Distributions. Click Edit Parameters and enter Mean = 265 and Standard deviation = 12 then click OK. Click Left Tail in the plot area then click then change the area to 0.90. WebIn each case, sketch a shaded normal curve such that the area of the shaded region is equal to the probability. (a) z ≤ −1.4 Proportion: (b) z ≥ −1.4 Proportion: (c) z > 1.8 Proportion: (d) −1.4 ≤ z ≤ 1.8 Proportion: 2. Find the maximum of x in the bottom quartile.
