Image that a researcher examined how the people’s weights affect their salaries. She found that the correlation between weights (measured in lbs.) and salary range (measured in dollars) was .10. Had she measured the weight in kg instead, what would the correlation have been?
a. Above 0.10
b. Below 0.10
c. 0.10
Homework Answers
Answer
Option C is correct
There will be no change in the correlation coefficient because when we convert one variable from one unit to another unit, then there will be some fixed change in each data value of that particular variable
We use the standardization technique to find the standard value corresponding to each raw value, this helps in reducing the affect of change in units.
Therefore, we have absolutely no change in the correlation coefficient value and it will remain same.
option A and B are incorrect because correlation coefficient is neither decreased nor increased, but it remains same

Suppose you are interested in estimating how health affects productivity. Specifically, you are interested in the following regression: where Y, is a variable representing the income earned by person i, and X, is a variable representing the health of person i. Income is a fairly straightforward concept to capture. Health, however, is a more complex concept that can be measured in many different ways. For example, body mass index (BMI weight in kilograms, divided by height in meters squared) is...

12. A certain group of test subjects had pulse rates with a mean of 84.484.4 beats per minute and a standard deviation of 11.211.2 beats per minute. Use the range rule of thumb to identify the limits separating values that are significantly low or significantly high. Is a pulse rate of 56.856.8 beats per minute significantly low or significantly high? Significantly low values are nothing beats per minute or lower. (Type an integer or a decimal. Do not round.) 14....

1. In the regression equation, the value that gives the amount by which Y changes for one unit in X is called the (a) coefficient of correlation. (b) coefficient of determination. (c) slope. (d) intercept. 2. For any two categorical variables, X and Y, the best way to determine if they are related is to (a) calculate the correlation between X and Y. (b) draw a scatterplot of the X and Y values. (c) make a two-way table of the...
