Please use R, Python or by hand
A student looks their horoscope rating every morning before taking an exam. The student keeps a log of the horoscope ratings and the exam performance. This is the log:
H = [3, 4, 9, 10, 6, 7]
E = [80, 90, 75, 95, 85, 85]
Test if least squares regression produces a significant F statistic:
F = MSRegression
MSResidual = (SSY −SSE)/k SSE/(n−k−1) a)
What conclusion can you arrive at?

Student stress at final exam time comes partly from the

A random sample of 200 BCOM students from recent years was taken
and their percentage grades on assignments, midterm exam, and final
exam were recorded. Let’s examine the ability of midterm and
assignment grades to predict final exam grades.
The data are shown here:
