From the gaussian (normal) error curve, what is the probability that a result from a population lies between 0 and +1σ of the mean?

0.3413

Step-by-step explanation:

We know that in Gaussian (normal) curve, to find probability we can use standard normal distribution table.

Here X is normal and we have to find the probability such that the population lies between 0 and sigma

i.e. this probability equal to the area to right of 0 and to the right of 1

From std normal distribution table we find that this area

Hence required prob

d

step-by-step explanation:

given

y + 3 = - 4(x - 2) ← distribute the parenthesis

y + 3 = - 4x + 8 ( subtract 3 from both sides )

y = - 4x + 5 → d
