Answer:
Step-by-step explanation:
X squared statistic , degrees of freedom(df) and p value are given.
We want to assess whether given variables are normally distributed or not. That means goodness of fit test.
Decision rule -
If p value is less than or equal to alpha (level of significance ) then variable is not normally distributed otherwise it is normally distributed.
That means p value is so small implies that variable is not normally dustributed.
Claim amount , household income, deductible amount and coverage amount have pvalue = 0 , it is so small. Hence all these variables are not normally distributed.
Similarly if p value is so small then the given 2 variables are not independent, otherwise they are independent.
For checking the statistical relationship between claim amount and income , it is given that pvalue =0
Hence these variables are dependent that means they have statistical relationship.
Similarly, for checking statistical relationship between claim type and marital status it is given that
p value = 0.3822479 which is a way larger .Hence we say that claim type and marital status are independent that means they don't have statistical relationship.
