- Probability of Correlation;
This is the “p-test page 1, p-test page 2, and the P Value Correlation Guide” in the Supplemental Area. Example 10-1 in the book
We have made a process improvement changing the average dry time from 121 minutes to 112 minutes. What is the Probability of Correlation or “Null Hypothesis of No Change”. Stated another way, what is the probability of they are from the same data set and there has been no change. Hence, proving the probability they are not from the same data set implies that are from a different data and therefore the change is real. Do we believe the improvement is real and not just a statistical random improvement?
Again, use the formula and colored chart from “P-Test page 1, P-Test page 2, and P-Value Correlation Guide” in the Supplemental area. Use the Chart Example 10-1 in the Book
X1 = 121
minutes
Sigma1 = 8
minutes
Sample Size 1 = 10
X2 = 112 minutes
Sigma2 = 8
minutes
Sample Size 2 = 10

I need help with Calculate the P-value at the bottom of the page. Thank you! To test the belief that sons are taller than their fathers, a student randomly selects 13 fathers who have adult male children. She records the height of both the father and son in inches and obtains the following data. Are sons taller than their fathers? Use the α = 0.05 level of significance. Note: A normal probability plot and boxplot of the data indicate that...

P-value is the probability, computed assuming H0 is true, that the test statistic would take a value as extreme or more extreme than that actually observed. Given the sample at hand, it is the smallest level of significance at which H0 would be rejected. It depends on the sample (hypotheses as well) and is hence also a test statistic. Generate 50 samples of size n=10 from a normal distribution with mean μ=1 and variance σ2=4. For each sample, use the...

Regression and Correlation Methods: Correlation, ANOVA, and Least Squares This is another way of assessing the possible association between a normally distributed variable y and a categorical variable x. These techniques are special cases of linear regression methods. The purpose of the assignment is to demonstrate methods of regression and correlation analysis in which two different variables in the same sample are related. The following are three important statistics, or methodologies, for using correlation and regression: Pearson's correlation coefficient ANOVA...

Cadmium, a heavy metal, is toxic to animals. Mushrooms, however, are able to absorb and accumulate cadmium at high concentrations. A government set a safety limit for cadmium in dry vegetables at 0.5 parts per million (ppm). The cadmium levels in a random sample of one species of edible mushroom are in the accompanying data set. At the 10% significance level, do the data...
