6. One hundred draws will be made at random with replacement from the box

[1 6 7 9 9 10]

PART I:

a) Find the expected value and the standard error for the sum of 100 draws

b) The sum of 100 draws is between 650 and 750 with a chance of about

1% 10% 50% 90% 99%

Show work for your answer by drawing the normal curve.

PART II:

a) Find the expected value and the standard error for the percentage of tickets marked by “9” in 100 draws. Make a box model.

a) What is the chance that the percentage of tickets marked by “9” is less than 40% ?

Show work using the normal curve.
