    A force of 16.0 newtons is sufficient to set a box that is at rest into motion. If the coefficient of static friction is 0.380, what is the normal force acting on the box?

    6. X has a normal distribution with a mean of 80.0 and a standard deviation of 3.5. Find the following probabilities: (A) P(x < 77.0) (B) P(75.0 < x < 85.0) (C) P(x > 85.0) (Points : 6) I think I have the first two but I am stumped on the third one. Thank

    I have no idea on how to answer this question... "Use technology or a standard normal distribution table to find the area to the left of z=1.58. Do I plug in 1.58 in my calculator to find the answer?

    We have a group of 75 people and for their raw scores, you are given the Mean (M = 30) and variance (VAR = 16). Assuming a normal distribution of scores, what is the probability of randomly selecting a score between 27 and 31 for this group?
