Question

The slope of the estimated regression line (b1) is a sample statistic, since, like other sample statistics, it is computed from the sample observations.

True or False

Answer 1

The slope of the estimated regression line (b1) is a sample statistic, since, like other sample statistics, it is computed from the sample observations.

Its answer is True

Because slope value is depends upon

Correlation coefficient, standard deviation of x and standard deviation of y

And correlation coefficient, standard deviation of x and the standard deviation of y are all sample statistics hence slope also sample statistics

Formula for slope is

b =r * (sd (y) /sd(x))

r is correlation coefficient

sd (y) standard deviation of y

And

sd (x) standard deviation of x
