Q.15 - The Practice of Statistics for AP

Question

When asked to explain the meaning of the P-value in Exercise 13, a student

says, “This means there is only probability 0.01 that the null hypothesis is true.” Explain clearly why the student’s explanation is wrong.

Step-by-Step Solution

Answer

The student’s explanation is wrong. 

Step 1: introduction

The null hypothesis is a normal factual hypothesis which recommends that no measurable relationship and importance exists in a bunch of given single noticed variables, between two arrangements of noticed information and estimated peculiarities.

Step 2: explanation

 “This means there is the only probability $0.01$ that the null hypothesis is true.”

This is incorrect as The null hypothesis can either be true or false which is probability $1$or $0$.
