X = velocity of plane
y = velocity of wind
x - y = 1680/5 = 336 mph .....(1) [ plane flying against the wind]
&
x + y = 1680/4 = 420 mph....(2) [ plane flying with the wind]
Adding (1) and (2) to eliminate y gives
2x = 756
x = 378 mph is the speed of the plane with no wind.

Given that a sample of 150 were asked whether or notthey supported capital punishment.
3)
we prepare contingency tab
Expected = 50 50 50
Chisquare = 4
chi square 2 2 0 4
p value 0.135
Since p >0.05 we accept H0
a. distribution is uniform
