A company is considering implementing one of two quality control plans for monitoring the weights of automobile batteries that i

t manufactures. If the manufacturing process is working properly, the battery weights are approximately normally distributed with a specified mean and standard deviation.
Quality control plan A calls for rejecting a battery as defective if its weight falls more than 2 standard deviations below the specified mean.

Quality control plan B calls for rejecting a battery as defective if its weight falls more than 1.5 interquartile ranges below the lower quartile of the specified population.

Assume the manufacturing process is under control.
a) What proportion of batteries will be rejected by plan A?
b) What is the probability that at least 1 of 2 randomly selected batteries will be rejected by plan A?
c) What proportion of batteries will be rejected by plan B?

Cost of goods sold         23,704     24,832

Interest                               1,230       1,584

Dividends                           1,200         600

Depreciation                     2,609       2,814

Administrative expenses 7,040       6,820

Cash                                  3,671       2,969

Inventory                          3,968       4,503

Accounts payable            2,325       3,760

Long-term debt               19,105    25,900

Accounts receivable        4,601        5,318

Common stock             22,600      19,800

Net fixed assets            41,260       42,110

Cash Flow from operations:

                                          2020        2019

Revenues                     $42,629    $37,911

Cost of goods sold         23,704     24,832

Interest                               1,230       1,584

Administrative expenses 7,040       6,820

Net cash flow                      $10,655

Working capital adjustment:

Inventory                                    535 (-3,968 + 4,503)

Accounts payable                  (1,435) (-2,325 + 3,760)

Accounts receivable                  717  (-4,601 + 5,318)

Net cash from operations $10,472

Total debt:

Long-term debt = $19,105

Current debt =         4,601

Total debt =         $23,706

Cash flow-to-debt ratio = Total debt/Net cash from operations

= $23,706/$10,472

= 2.26

b) The cash flow-to-debt ratio is the ratio of a company's cash flow from operations to its total debt, which shows how long (2.26 years) it takes the company to repay its debt if it devoted all of its cash flow to debt repayment.
