We have been given to verify the conditions used for inference in chi-square test.

The expected value of the number of sample observations in each level of the variable is atleast $5$.

In this case,all the expected value is greater than $5$.

So,the conditions for inference are met.

We have been given that,

Chi-square value =$6.62$

Degree of freedom =$6-1=5$

For chi-square value$0.83$the P-value is$0.975$

For chi-square value $7.29$ the P-value is $0.20$

So,for chi-square value $6.62$,the P-value lies between $0.20and0.975$

We have been given that,

Chi-square value =$6.62$

Degree of freedom =$6-1=5$

In calculator, give the value of chi-square =$6.62$and

degree of freedom=$6-1=5$

We get the P-value =$0.25$

We have been given that,

Chi-square value =$6.62$

Degree of freedom = $6-1=5$

$\mathrm{Î\pm }=0.01$

In calculator, give the value of chi-square =$6.62$and

Degree of freedom=$6-1=5$

$\mathrm{Î\pm }=0.01$

We get the P-value =$0.25$
