A) the z score for 95% is 1.96
Multiply by the deviation:
1.96 x 0.005 = 0.0098
Now add and then subtract that from the mean:
4.035 - 0.0098 = 4.0252
4.035 + 0.0098 = 4.0448
The interval is (4.0252, 4.0448)
B) 4.035 +/- 1.96 x sqrt( 0.005/sqrt(25))
= 4.035 +/-0.00196
Answer: ( 4.033, 4.037)
C) the conclusion is that both 4.020 and 4.055 are out of the range.
4.020 is below the lowest range and 5.055 is higher than highest range.

Answer:
28
Step-by-step explanation:
p(x)=-2(x-9)^2+100
Let x= 15
p(15)=-2(15-9)^2+100
Parentheses first
= -2 ( 6) ^2 + 100
Then exponents
= -2 * 36 + 100
Then multiply
= -72 + 100
Then add
=28
