The sem for an achievement test is 2.45. jonny scores 100 and we assume that 68% of the time his true score falls between + or - 1 sem. this means the confidence interval would be between what?

113.1

step-by-step explanation:

v=4

3πr3=4

3·π·33≈113.09734

step-by-step explanation:

given the equation is 8+9z=-6, the first step would be to subtract the 8 from both sides:

8+9z-8=-6-8

since 8 minus 8 = 0, this would cancel out the 8. and since -6 minus 8 equals -14, the equation would look like this

9z = -14

210/22 = 9.55

since he can't take part of a person to the game the answer is 9 people

hope this !
