Answer #1

Solution:- d) Increase bias.

a) Increase sample size.

As the sample size increases, the t value become greater and that contribute to the significance of differences.

b) Increase the size of the difference.

As the size of differences increases, the t value become greater and that contribute to the significance of differences.

c) Decrease variation within the group.

As the variation is decreases, the t value become greater and that contribute to the significance of differences.

d)  Increase bias.

Increasing the bias does not contribute to the significance of differences.
