yes .But in this problem we need not find as the critical value is not given .As the question is just to find the Chi square value we can do only up to this .If it is to check the goodness of fit we can compare the table value and the calculated value.
It seems we can do two more steps , finding degree of freedom and check table value to determine whether to reject null hypothesis

Hello ma'am I have a exam on coming 31 can you please tell me few important questions? I know m asking alot but still 😅

you can round off the answer to two digits
