Question

The time it takes to preform a task has a continuous uniform
distribution between 43 min and 57 min. What is the the probability
it takes between 47.6 and 54.7 min. Round to 4 decimal
places.

*P*(47.6 < *X* < 54.7) =

Answer #1

The lengths of a professor's classes has a continuous uniform
distribution between 50.0 min and 52.0 min. If one such class is
randomly selected, find the probability that the class length is
less than 51.3 min.
P(X < 51.3) =

part 1) The lengths of a professor's classes has a continuous
uniform distribution between 50.0 min and 52.0 min. If one such
class is randomly selected, find the probability that the class
length is less than 50.9 min.
P(X < 50.9) =

The lengths of a professor's classes has a continuous uniform
distribution between 50.0 min and 52.0 min. If one such class is
randomly selected, find the probability that the class length is
more than 50.2 min.
P(X > 50.2) =

Assume the time to complete a task has a normal distribution
with mean 20 min. and standard deviation 4 min.
Find the proportion of times that are BETWEEN 15 and 25
minutes?
Note: Enter X.XX AT LEAST ONE DIGIT BEFORE THE DECIMAL, TWO
AFTER and round up. Thus, 7 is entered as 7.00, 3.5 is entered as
3.50, 0.3750 is entered as 0.38

The continuous random variable X, has a uniform distribution
over the interval from 23 to 43. Given that z is a standard normal
random variable, what is the probability of z being greater than
-1.53? if the area to the left of z is 0.166, what is the value of
Z? if the area between this z and its negative value, –z is an area
of 0.97, what is the value of z?
