a)
We first get the z score for the critical value. As z = (x - u) / s, then as
x = critical value = 5
u = mean = -1
s = standard deviation = 10.9
Thus,
z = (x - u) / s = 0.550458716
Thus, using a table/technology, the right tailed area of this is
P(z > 0.550458716 ) = 0.291002393 [ANSWER]

b)
We first get the z score for the critical value. As z = (x - u) / s, then as
x = critical value = -2
u = mean = -1
s = standard deviation = 10.9
Thus,
z = (x - u) / s = -0.091743119
Thus, using a table/technology, the left tailed area of this is
P(z < -0.091743119 ) = 0.463451069 [ANSWER]

c)
They beat the spread if relative to the spread the score is at least 0.
We first get the z score for the critical value. As z = (x - u) / s, then as
x = critical value = 0
u = mean = -1
s = standard deviation = 10.9
Thus,
z = (x - u) / s = 0.091743119
Thus, using a table/technology, the right tailed area of this is
P(z > 0.091743119 ) = 0.463451069 [ANSWER]
