The area is about 0.000405. The value is not doubled because it is a one-tailed test. Because it is less than the significance level of 0.01, it was correct to reject the null hypothesis. Problem 3 – Cats and Dogs. For the scenario, students should work independently to write the null and alternative hypotheses.

However, a more general solution is to consider the integral of the concentration over time curve, known in pharmacokinetics as the “area under the curve” or “AUC” for short. This integral can be solved as: 6 Thus, Q = x0 /AUC, showing that the clearance equals the dose divided by the area under the curve.

The area under the ROC curve is a commonly used summary statistics representing the skill of the forecast system. The area is standardised against the total area of the figure such that a perfect forecast system has an area of one and a curve lying along the diagonal (no information) has an area of 0.5.

What is the significance of the area under the curve for the force versus time graph? How does the area under the curve for the force-time graph compare to the change in momentum? What are some possible reasons why the calculated change in momentum is not the same as the measured impulse?

(In fact, it is sometimes called the “Bell Curve”.) Normal distributions are symmetric about their mean. Normal distributions follow the 68-95-99.7 rule: (Approximately) 68% of the area under the curve is within one standard deviation of the mean (Approximately) 95% of the area under the curve is within two standard deviations of the mean

The critical point(s) divides the whole area under a distribution curve into rejection and non- rejection regions. d. The significance level, denoted by α, is the probability of making a Type I error, that is, the probability of rejecting the null hypothesis when it is actually true. e. The nonrejection region is the area where the null ...

C.Shade the area under the curve that gives the P-value for the result = 30.2%. (Note that we are looking for evidence that spending is less that null hypothesis states.) For 18 and 19, each of the following situations calls for a significance test for a population mean .

This is the area to the left of –0.8. Because the total area under the curve is 1, the area lying to the right of –0.8 is 1-0.2119=0.7881. A. Standardize first, and we can get –1.7 < x < -0.2. Then, look at the table, the total area should be .4207 – .0446= .3761. D. We want to find the score x with area 0.03 to its right under the ...
