collect data exhibiting a relatively linear trend, find the line of
best fit, plot the data and the line, interpret the slope, and use
the linear equation to make a prediction. Also find r2 (coefficient
of determination) and r (correlation coefficient). Discuss your
findings. Your topic may be that is related to sports, your work, a
hobby, or something you find interesting.

Expert Solution
The regression equation : y = 4.17x - 0.26
Slope = 4.17
For unit of increase in X(1% = 0.01) they variable Y would increase by 0.417 units
let us make a prediction x = 80% ( GPA of student with 80% attendance )
y = 4.17(0.80) - 0.26 = 3.076

Determine and interpret the linear correlation coefficient, and
use linear regression to find a best fit line for a scatter plot of
the data and make predictions. Scenario According to the U.S.
Geological Survey (USGS), the probability of a magnitude 6.7 or
greater earthquake in the Greater Bay Area is 63%, about 2 out of
3, in the next 30 years. In April 2008, scientists and engineers
released a new earthquake forecast for the State of California
called the Uniform...

A plot of detector signal versus ppm Ca2+ yielded a
best fit straight line with a slope of 1.38 volts/ppm. Multiple
blank measurements resulted in a standard deviation of 0.18 volts.
Using a 2:1 signal-to-noise ratio criteria, calculate the detection
limit for Ca2+ in ppm when this method is employed.
Thanks!
