Problem Set 1 - Area Under Normal Curve
Find the area under the standard normal distribution curve to the left of z = 2.09.
round(pnorm(2.09), 4)
Find the area under the standard normal distribution curve to the right of z = -1.14.
round(pnorm(-1.14, lower.tail = FALSE), 4)
Find the area under the standard normal distribution curve between z = -162 and z = 1.35
Find the probability for each
print(round(pnorm(2.53), 4) - round(pnorm(0), 4))
Find the z value such that the area under the standard normal distribution curve between 0 and the z value is 0.02123.
qnorm(0.7123)
I am having trouble keeping up with what is happening in class and what we are supposed to be doing, potentially on account of ADHD. Apologies.
Between z = 1.90 and z = 1.23.
pnorm(1.90) - pnorm(1.23)
To the left of z = -215 and to the right of z = 1.62
pnorm(-2.15) + pnorm(1.62, lower.tail = FALSE)
Find two z values so that 48% of the middle area is bounded by them.
qnorm(0.48)
Find P(-1,
