or by use of excel function of Correl (array 1 ,array 2), the value of correlation co-efficient fall in between -1 to +1,
Here, correlation value +0.892 , indicate highly positive correlation among these two factors.

The data below represents height in inches/weight in pounds. Clearly identify the dependent and independent variables as well as the domain and range. Choose any two points from the data using different independent variables and use those two points to determine the rate of change (slope). Then, using the dependent data value of -500 as your initial value, write an equation for the linear function model. Predict what you expect at a height of 75". inches/pounds 60" - 105, 110...

Maintaining a healthy weight is important for women’s health. Some physicians recommend being back to your pre-pregnancy weight six months after giving birth. Public health officials are interested in whether this is a realistic goal. Do the women in North Carolina weigh more than their pre-pregnancy weight six months postpartum? In other words, is the six months post-pregnancy weight greater than their pre-pregnancy weight? Use a paired samples t-test to compare pst6wght (variable 1) and prewght (variable 2). This uses...

Problem 1 The following data are from a research project on the effectiveness of a drug in reducing LDL cholesterol levels. While some patients in the study are assigned to the drug, others were given a placebo. Because the information about who is receiving the actual drug is kept confidential from those taking LDL measurements, that information is kept in a separate data set. Given below in Data Set A are the initial LDL cholesterol level of each individual before...
