So, coming to the a part, this is a c square goodness of fit test problem.
00:15
Then come to the b part, the expect frequency for the outcome of 5 is 1 by 6 multiply by 300 which is equals to 50.
00:39
Now moving to the c part, the g square test statistic is calculated as follows, x square is equals to sigma observed minus expected whole square divide by expected.
00:57
So, here we get, we say x square is equals to 44 minus 50 divide whole square divide by 50, then here 48 minus 50 whole square divide by 50, then 47 minus 50 whole square divide by 50, then add 53 minus 50 whole square divide by 50, then 52 minus 50 whole square divide by 50 plus 56 minus 50 whole square divide by 50.
01:42
So, here we can say that x square is equals to 4 .96.

Now moving to the d part, using a significance level of 5 percent and 5 degrees of freedom...
