change the pounds of force to # of std deviations above or below the mean.

? what i dont get what ur saying

200 is the mean (the average)
and the standard deviation is 3

so make it 3lbs = standard deviation 200

so what is 194 ? it is two standard deviations below the mean (i.e. 200 - 2*3)

its 194 and 206

yes, and 194 is 2 std dev below the mean
what is 206 ?

above the mean is 206

so B is the one thats not true

itll be 2 going up cause the standard deviation is 3

500 is half of 1000

About 500 springs could withstand 200 lbs or more of force.
is true.

so that cant be the answer were looking for which is not true

let's look at choice B
About 950 springs could withstand between 194 and 206 lbs of force.

should i find half of 950

half of 950 is 475

so to check
950 are between -2 and +2 standard deviations
what is 95% of 1000 ?

yea and its still enough to with stand it

would i do 1000/.95

its 950

in other words, choice B is correct
95% (of the 1000 springs) are between -2 and +2

so choice B and C are correct so cross those out

25

no

answer is D thanks

so the answer i should choose is D

no, the answer is not D. read what I posted up above.

oh i see it so its A
