Question

An elevator has a placard stating that the maximum capacity is 1392 lblong dash8 passengers. So, 8 adult male passengers can have a mean weight of up to 1392 divided by 8 equals 174 pounds. If the elevator is loaded with 8 adult male passengers, find the probability that it is overloaded because they have a mean weight greater than 174 lb. (Assume that weights of males are normally distributed with a mean of 178 lb and a standard deviation of 32 lb.) Does this elevator appear to be safe? A. the probability the elevator is overloaded is? b. does the elevator appear to be safe

Answer #1

An elevator has a placard stating that the maximum capacity is
1280 lblong dash8 passengers. So, 8 adult male passengers can have
a mean weight of up to 1280 divided by 8 equals 160 pounds. If the
elevator is loaded with 8 adult male passengers, find the
probability that it is overloaded because they have a mean weight
greater than 160 lb. (Assume that weights of males are normally
distributed with a mean of 162 lb and a standard deviation...

An elevator has a placard stating that the maximum capacity is
1200 lblong dash8 passengers. So, 8 adult male passengers can have
a mean weight of up to 1200 divided by 8 equals 150 pounds. If the
elevator is loaded with 8 adult male passengers, find the
probability that it is overloaded because they have a mean weight
greater than 150 lb. (Assume that weights of males are normally
distributed with a mean of 160 lb and a standard deviation...

An elevator has a placard stating that the maximum capacity
is
1240 lb —88 passengers. So,
88 adult male passengers can have a mean weight of up to
1240 divided by 8 equals 155 pounds.1240/8=155 pounds.
If the elevator is loaded with
88
adult male passengers, find the probability that it is
overloaded because they have a mean weight greater than
155
lb. (Assume that weights of males are normally distributed with
a mean of

An elevator has a placard stating that the maximum capacity is
1610 lb—10 passengers. So, 10 adult male passengers can have a
mean weight of up to 1610 divided by 10 equals 161
pounds.1610/10=161 pounds. If the elevator is loaded with 10 adult
male passengers, find the probability that it is overloaded
because they have a mean weight greater than 161 lb. (Assume that
weights of males are normally distributed with a mean of 164 lb and
a standard deviation...

An elevator has a placard stating that the maximum capacity is
1376 —8 passengers.
So, 8 adult male passengers can have a mean weight of up to
1376/8=172 lb.
If the elevator is loaded with 8 adult male passengers, find
the probability that it is overloaded because they have a mean
weight greater than 172 lbs.
(Assume that weights of males are normally distributed with a
mean of 174 lb and a standard deviation of 28 lb.)
Does this elevator...

An elevator has a placard stating that the maximum capacity is
2475 lb —15 passengers. So, 15 adult male passengers can have a
mean weight of up to 2475/15=165 pounds. If the elevator is loaded
with 15 adult male passengers, find the probability that it is
overloaded because they have a mean weight greater than 165 lb.
(Assume that weights of males are normally distributed with a mean
of 167 lb and a standard deviation of 35 lb.) Does this...

An elevator has a placard stating that the maximum capacity is
1580 lb - 10 passengers. So, 10 adult male passengers
can have a mean weight of up to 1580 divided by 10 equals 158
pounds. If the elevator is loaded with 10 adult male passengers,
find the probability that it is overloaded because they have a mean
weight greater than 158 lb. (Assume that weights of males are
normally distributed with a mean of 168 lb and a standard...

an elevator has a placard stating that the maximum
capacity is 1944 lbs- 12 passengers. So, 12 adult male passengers
can have a mean weight of up to 1944/12 =162 pounds. If the
elevator is loaded with 12 adult male passengers, find the
probability that it is overloaded because they have a mean weight
greater than 162 lbs. (Assume that weights are normally distributed
with a mean of 166 lb and a standard deviation of 33 lb.) Does the
elevator...

An elevator has a placard stating that the max capacity is
2028lb- 12 passengers. So, 12 adult males passengers can have mean
weight up to 169lbs. If the elevator is loaded with 12 adult males,
find the probability that it is overloaded because they have a mean
weight greater than 169lb. Assume weight of males normally
distributed with a mean of 175lb and standard deviation of 27lb.
