Q-5) Daily demand for water pumps at local auto part distributors is normally distributed with a mean of 60 units and standard deviation of 5 units per a day. This distributer purchase their water pump from a manufacture in Michigan. The delivery time is exactly 3 days after order. What Is the reorder point to make sure not more than 5% of customers will not receive a water pump

option 1 is correct.

step-by-step explanation:

y varies inversely with x and constant of variation is 4

the equation will be:

y = k/x

where k =4 so,

y = 4/x

if we put values of x of option 1 in the above equation and find values of y

y = 4/-2 => y =-2

y = 4/-1 => y = -4

y = 4/1 => y = 4

y = 4/2 => y =2

so, all the values of x and y are correct.

if we put values of x given in other options and find value of y we cannot find whole table satisfying the equation.

hence option 1 is correct.
