Answer:
38.2 %
Step-by-step explanation:
120/100 = 1.2 (average time)
(1.2 - 1.5)/1 = -.3
z table value for "-.3" is .3821
csc(x) is the reciprocal of sin(x)
Since sin(x) = 6/7
Then to find csc (x) reciprocal to the value of sin(c)
csc(x) = 7/6
The answer is the first choice
Although I don't see 1950, 1988, or 2010 on your model, I did calculate the average for 1972, 1982, 1992, and 2002: the average that I got was 1.6025 (this answer has not been rounded due to the fact that I don't know if you need to round it)
hope this helps
