Please assist with question 10 and 11

10. Further to the information provided in question nine (9) above, we are informed that nails produced that are shorter than the minimum acceptable length have to be scrapped. Consider that 4.8cm is still the minimum threshold for acceptable nail length. If the cost to produce one nail is 45 cents, how much does the company incur in Rand losses due to scrapping? (4 marks)

A. R247.70

B. R347.91

C. R237.60

D. R471.99

11. Further considering information given in questions nine (9) and ten (10), if no more than 2% of nails are to be scrapped, what should the new mean be set at in millimeters? Assume that the standard deviation remains unchanged. (4 marks)

A. 51.28

B. 52.21

C. 68.92

D. 69.28
