Question

For the conj ecture "The average age of students in this class is 22", the null hypothesis is:

A) We accept the hypothesis that the average age of students in this elass is 22.

B) The average age of students in this class is 22.

C) The average age of students in this class is not 22.

Answer 1

Answer:

Option B)

$H_0 = \text{The average age of students in this class is 22.}$

Step-by-step explanation:

We are given the following information the question:

The conjecture "The average age of students in this class is 22"

We have to design the null hypothesis based on this conjecture.

Null Hypothesis

• The null hypothesis always state equality to the population.

• It states that the sample is taken from the population and the sample has same statistic as the population.

The null hypothesis can be designed as:

$H_0 = \text{The average age of students in this class is 22.}$
