b) 0.5
c) 0.8333
d) The mean is 250 and the standard deviation is 51.96.
Step-by-step explanation:
An uniform probability is a case of probability in which each outcome is equally as likely.
For this situation, we have a lower limit of the distribution that we call a and an upper limit that we call b.
The probability of finding a value of X higher than x is:
The probability of finding a value of X between c and d is:
The mean and the standard deviation are, respectively:
A random variable follows the continuous uniform distribution between 160 and 340.
This means that
a)
b)
c)
d)
