Question

Using your own words, what does it mean if we fail to reject the null hypothesis? What if we reject the null hypothesis? What does that mean? The key to answering this discussion posting is to use your own words to describe what it means to reject or fail to reject the null hypothesis. Don't use the terms in the textbook or online presentation. Using an example you personally create may help explain the difference. Thank you for your help.

Answer 1

Suppose,

We claim that, Average height of students in the class is greater than 165 cm.

Hence, Our hypotheses will be,

Null hypothesis(Ho): Mean(μ)=165 cm

vs

Alternative hypothesis(Ha): Mean(μ) > 165 cm (Claim)

Now,

Meaning of we fail to reject(i.e., accept) the null hypothesis is conclude that, "Average height of students in the class is equal to 165 cm."

and if we reject the null hypothesis(i.e., accept alternative hypothesis) means conclude that, "Average height of students in the class is greater than 165 cm."

Thank you.
