(1.5 points) Neatly label the Normal curve below with the number and symbol for the mean you use in your null hypothesis ((0) and the sample mean (). Also shade and label the appropriate part of the curve which shows the P-value. (1.5 points) Neatly label the Normal curve below with the number and symbol for z = 0, and the test statistic (z0 ...

Use the given sample data to find the P-value for the significance test. Give an . interpretation of the P-value. n1 = 200, = 0.10, n2 = 200, = 0.08. A) P-value = 0.2119; If there is no difference in the proportions, there is about a 21.19% chance of seeing the observed difference or larger by natural sampling variation.

The p-value is the area to the left of the sample mean is given as 16. Graph: ... Press ENTER. A shaded graph appears with z=-2.08 (test statistic) and p=0.0187 (p-value). Make sure when you use Draw that no other equations are highlighted in Y = and the plots are turned off. When the calculator does a Z-Test, the Z-Test function finds the p-value by doing a normal probability calculation ...

The P-value lies between 0.0005 and 0.001. Software gives the value P=0.0053. “The improvement in score was significant (t=3.86, df=19, p=0.00053).” Example 5 A 90% confidence interval for the mean improvement in the entire population requires the critical value …
What Is A p Value and What Does It Mean
The p value of this study was 0.08. If the researchers set the alpha level at 0.05, they would conclude that there was no significant difference between the annual incomes of hospital and community based nurses, since the p value of 0.08 exceeded the alpha level of 0.05. However, if the alpha level had been set at 0.10, the p value of 0.08 would be less than the alpha level and the researchers ...
