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

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!
