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.

Option B)

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 can be designed as:

multiplication is multiplication.   it might feel harder depending on what level of math you are in, but generally it will be the same old stuff, while implementing some new concepts and methods of solving work.

180°

step-by-step explanation:

sum of equilateral triangle=180°

< n=60°

< m=120°°[angle supplementary of equilateral angle]

< m+< r+< x=360°(sum of exterior angle of triangle)
