Apparently there's smart people on ATRL (who would have thought), so y'all can discuss your Math needs here. We can survive this together.

help me. It's Statistics, Standard Normal Distribution.

The fracture strength of a certain type of manufactured glass is normally distributed with a mean of 564 MPa with a standard deviation of 17 MPa.

(a)
What is the probability that a randomly chosen sample of glass will break at less than 564 MPa? (Round your answer to 2 decimal places.)

Probability

(b)
What is the probability that a randomly chosen sample of glass will break at more than 585 Mpa? (Round your answer to 4 decimal places.)

Probability

(c)
What is the probability that a randomly chosen sample of glass will break at less than 592 MPa? (Round your answer to 4 decimal places.)

I was until I entered Pre-calc and used almost half the alphabet in a equation
Whoops read the stuff below the Subtitle

Bye.

that's not the right answer.

good luck with statistics

You have to convert the MPa values to Z values and then use the standard normal distribution table to find the probabilities. The first one should be a fifty percent chance, because it is the mean of the sample. The other two will be fifty percent plus the value you find in the table!

Am I the only one who calls it MathS? but no I am not

PM if you're good in statistics, I'll give you a BJ.

I don't know much about algebra but I know, 1+1 = 2

Hopefully, it's easier than AP Calc BC ... it seems foreign to me now lol, but that's okay.

I'm good AT math, not in it.

Please tutor me, you little genius you.

Probability 0.50

the thirst

I have 5 hours to finish these.

now we know why I'm not an English major.

Im done with Calc [thank god], never going back to that again.

I'm a flop at math. I won't ever get a career anywhere; time to sell crack.
