Answer:
Accept the null hypothesis if it is two tailed test.
Step-by-step explanation:
The null hypotheses can only be accepted if it is a two tailed test and calculated chi square must be less than the critical value of chi square.
Then the difference between the the observed and expected frequencies will be zero.
where
H0 : σ²-σ²= 0 Ha: σ²-σ²≠0
For this the critical region would be greater than the calculated value of chi square. If so we will accept the null hypothesis and reject the alternative hypothesis.
Answer:
The answer is
<h3>2 to 1 significant figure</h3>
Step-by-step explanation:

To solve the question first convert the mixed fraction to an improper fraction
That's

So we have

Find the LCM of the fractions
The LCM of 5 and 4 is 20
That's


= 2.15
We have the final answer as
<h3>2 to 1 significant figure</h3>
