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.
1. x/6>3 multiply both sides by 6
x>18
So a. and c. are both greater than 18
2.
-4x<32 divide both sides by -4 (and remember to reverse direction of inequality sign because of multiplication/division by a negative value!)
x>-8
So three value of this infinite set are -7, -6, -5 :P
3.
x/6≥3 multiply both sides by 6
x≥18
So three value of this infinite set of solutions are 18,19,20
