A health research institute collects information from 20 individuals on the number of years they have spent smoking cigarettes,
olga55 [171]

The correlation coefficient of the health research institute data measures the relationship between the age and the years of the smokers

The correlation coefficient is 0.53

<h3>How to calculate the correlation coefficient</h3>

The correlation coefficient (r) is calculated as:

r = \frac{n(\sum xy) - \sum x \sum y}{\sqrt{[n \sum x^2 - (\sum x)^2][n\sum y^2 - (\sum y)^2}}

Using the given parameters, we have:

r = \frac{20 *8249 - 1257* 116}{\sqrt{[20 * 98823 - 1257^2][20 * 836 - 116^2}}

Evaluate the exponents

r = \frac{20 *8249 - 1257* 116}{\sqrt{[20 * 98823 - 1580049][20 * 836 - 13456}}

Evaluate the products

r = \frac{164980 - 145812}{\sqrt{[1976460 - 1580049][16720 - 13456}}

Evaluate the differences

r = \frac{19168}{\sqrt{[396411*3264}}

Evaluate the product

r = \frac{19168}{\sqrt{1293885504}}

Evaluate the root

r = \frac{19168}{35970.6}

Evaluate the quotient

r = 0.53

Hence, the correlation coefficient is 0.53
