Step-by-step answer:
standard deviation (sigma) = 12 inches
mean (mu) = 90 inches.
For 36 years, the standard error of the mean is
e = sigma / sqrt(n) = 12" / sqrt(36) = 2".
Deviation from the mean
= 92.8 -90 = 2.8
Since the standard error of the mean follows the normal distribution, we have
Z=(92.8-90)/2 = 1.4
Looking up the normal distribution tables, or check R, we find
P(Z>1.4) = 1-P(Z<1.4) = 1-0.9192433 = 0.08075666
Answer: P(snowfall>92.8) = 0.0808 (to four decimal places)
A) J = (3/8)*(5/15 -6/15) = (3/8)*(-1/15) = (1/8)*(-1/5) = -1/40
.. K = (3/4)*(4/6 -5/6) = (3/4)*(-1/6) = (1/4)*(-1/2) = -1/8
B) (-1/40) +(-1/8) = -1/40 -5/40 = -6/40 = -3/20
C) The opposite of -3/20 is 3/20
D) Real world: I'm answering Brainly.com questions and one asks the opposite of -3/20.
