Suppose you have a random variable that is uniformly distributed between 80 and 667. What is the probability of observing a random draw greater than or equal to 314? Answer to three decimal place if necessary.

P(x>=314) = 354/588 = 0.602

Step-by-step explanation:

At first, we will find the sample space S

S = 667-80+1.  i.e 80 and 667 are included

S= 588, so we have total of 588 numbers in the series

now comes the number greater or equal to 314

we will get total of 354 number greater than or equal to 314

x = 667-314+1 = 354

p( number >= 314) = (numbers >= 314)/total sample space

p= 354/588

p= 0.602

an advantage of the standard deviation is that it increases as the dispersion of the data increases. e. the interquartile range is preferred when the data are not skewed or no have outliers. an advantage of the standard deviation is that it uses all the observations in its computation.

i dont understand the question? ?
