I. With the biweekly income variables and number of activities carried out by 6 people; find and analyze:
a) Linear dispersion diagram?
b) Correlation coefficient?
c) Perform a null hypothesis test that the correlation
coefficients
Linear in the universe are not significantly different from zero.

for the t & F test?
d) Linear regression equation for Ye?
e) Margin of error?
f) Estimation of the level of activities with an income of $ 1,600?
