address this challenge by creating defined criteria’s where we can evaluate the answers given against guidelines and reject answers that would not fit. If we could assume that on our ten point scale‚ five will be considered the point at which the business is not capable of producing profit or incurring losses‚ we would have defined the zero point and as such we would be able to quantitatively measure the elements on a continuous scale and the variables

a. Is it reasonable that the distribution of checking account balances approximates a normal distribution? Yes. Its reasonable because the sample size is large and and n -( increases the distribution of checking account balances approximates normal distribution. b.
