Q5 Can you help me solve this equation, I need all the steps to understand.

We are trying to determine the weight of athletes from their height. To do this, we observe the size X (in centimeters -cm) and the weight Y (in kilograms -kg) of 38 athletes. The following results are obtained:

For the height: an average \ (\ bar {x} \) = 183 cm with a corrected standard deviation sx = 8 cm

For the weight: an average \ (\ bar {y} \) = 70 kg with a corrected standard deviation sy = 3 kg

The corrected covariance is sxy = 22.8.

Determine the coefficient b1, slope of the regression line Y = b0 + b1X, and estimate the standard deviation of b1.
