Suppose 170 geology students measure the mass of an ore sample. Due to human error and limitations in the reliability of the balance not all the readings are equal. The results are found to closely approximate a normal curve with mean 83 g and standard deviation 3 g. Use the symmetry of the normal curve and the empirical rule as needed to estimate the number of students reporting readings between 74g and 92g

Secured loans are protected by collateral security. examples: title loans where the borrower uses the car title as collateral security interest rates are lower and repayments are longer therefore risk is low as a collateral security is given as guarantee to the bank in case of failure to pay the loanunsecured loans are not protected by collateral security but it is given on the creditworthiness of the borrower, trusting that she/he will pay on time. examples; payday loans is a short term loan where the borrower lends money from the bank and pays is back when the borrower receives his/her wages.interest rates are high and repayments are shorter. but the risk is high as no collateral security is given as a guarantee to the bank for payment of the loan
