17. the first five students who arrived for the tuesday lecture filled out a questionnaire on their attitudes toward statistics. the first five who were late for lecture were asked to fill out the same questionnaire. the appropriate design for testing the significance of the difference is

We are taking alternative and null hypothesis t- test

H₀: u1 = u2

if we reject the hypothesis and accept the alternative hypothesis than population means

H₁: u1 ≠ u2

In this test we need a significance level that is also called alpha level who reject or accept the null hypothesis.

were is the equation
