Answer: 0.2872
Step-by-step explanation:
Given : In a sample of 1000 randomly selected consumers who had opportunities to send in a rebate claim form after purchasing a product, 260 of these people said they never did so.
i.e. n= 1000 and x= 260
⇒ Sample proportion :
z-value for 95% confidence interval :
Now, an upper confidence bound at the 95% confidence level for the true proportion of such consumers who never apply for a rebate. :-
∴ An upper confidence bound at the 95% confidence level for the true proportion of such consumers who never apply for a rebate : 0.2872
1) Cancel out the common factor which in this case is 8
2)First apply exponent rule now cancel out the common factors which are n and n+7 leaving you with
3)Factorize cancel out the common factor in this case x+2 leaving you with
4) Factorize cancel out the common factor in this case 3w-1 leaving you with
