1. Answer: given: an average of 28 pounds
a.
Find z values corresponding to 27 and 31:
z=%2827-28%29%2F2=-1%2F2=-0.5
z=%2831-28%29%2F2=3%2F2=1.5
Find the area between z+=+-0.5 and z=+1.5
Table E gives us an area of 0.9332-0.30=0.6247=> The probability is 62.47%
b.
Find z values corresponding to 30.2
z=%2830.2-28%29%2F2=2.2%2F2=1.1 Find the area to the right of z+=1.1
it gives you an area of 0.1357=> The probability is 13.57%
If 3/5 are action and 1/4 are comedy then:
(3/5)+(1/4) are action or comedy
To add/subtract fractions you need a common denominator...
(3/5)*(4/4)+(1/4)(5/5)
(12/20)+(5/20)
17/20
So 17/20 (85%) of his collection are action or comedy not 4/9...
