To solve this problem, we have to make use of the standard
probability distribution tables for z test.
Since we are asked to find for the 72 percent level
confidence, then this means we are to look for the value of z which gives
(100-72)/2 = 14% on both sides of the tail.
So at 14% tail on one side, the z value is approximately:
1.08

Answer:
Step-by-step explanation:
2x3−34x2+131x+11
2x3−34x2+131x+11
=(x−11)(2x2−12x−1)
Answer:
(x−11)(2x2−12x−1)
Answer:
14
Step-by-step explanation:
To find the mean you add all the numbers and divide it by the amount of numbers there is so add
6+9+15+22+30+36=118
there is 6 number so divide 118 by 6
118/6=<span>19.6666666667 rounded to the nearest tenth it would be 20
So your mean would be 20
