The weekly incomes of shift foreman for a given industry follow a normal probability distribution. with a mean of $1,000 and a standard deviation of $100, what is the z-value for the income (called x) of a foreman who earns $1100 per week? for a foreman who earns $900 per week? in words, what do your results indicate?

There is a 0.2419% for a foreman to earn either $1,100 or $900

Explanation:

We calculate the probability of a normal distribution of 0;1

(X-mean)/deviation = Z

(1,100 - 1,000)/100 = 100/100 = 1

900 - 1,00/100 = -100/100 = -1

Given the zame Z value, we have the same probability of a foreman to earn 1,100 or 900

As we are asked for the foreman salary, wewill calcualte the Z for non cumulative, just the probability of a foreman to earn 1,100 or 900 dollars.

We look into the normal distribution table for the value of z = -1 or 1

0.002419707  = 0.2419%

i would have to say its c

so i don't know what video you're talking about, but here's some stuff steve jobs gave as advice.

- love what you do.

- the worst thing that could happen might turn out to be the best thing that could happen.

- follow your heart and trust it knows where it's going.
