If the owners of some kind of machinery intend to store it undercover, this is wise because it reduces the rate of depreciation.
<h3>Why should machinery be stored undercover?</h3>
Machinery lasts longer when it is protected from weather elements such as rain and sunshine. This reduces the rate at which it depreciates and becomes worn down.
Storing machines undercover is therefore wise because it protects the machinery from these weather elements.

Answer:
-79/53 - 38i/53
Step-by-step explanation:
Answer:
90% CI expects to capture u 90% of time
(a) This means 0.9 * 1000 = 900 intervals will capture u
(b) Here we treat CI as binomial random variable, having probability 0.9 for success
n = 1000
p = 0.9
For this case, applying normal approximation to binomial, we get:
mean = n*p= 900
variance = n*p*(1-p) = 90
std dev = 9.4868
We want to Find : P(890 <= X <= 910) = P( 889.5 < X < 910.5) (integer continuity correction)
We convert to standard normal form, Z ~ N(0,1) by z1 = (x1 - u )/s
so z1 = (889.5 - 900 )/9.4868 = -1.11
so z2 = (910.5 - 900 )/9.4868 = 1.11
P( 889.5 < X < 910.5) = P(z1 < Z < z2) = P( Z < 1.11) - P(Z < -1.11)
= 0.8665 - 0.1335
= 0.733
