Answer:
[tex]X \sim Unif (a=40, b=60)[/tex]
And for this case we want to find the probability density function and we know that is given by:
[tex] f(x) =\frac{1}{b-a}=\frac{1}{60-40}= \frac{1}{20}, 40\leq X\leq 60[/tex]
Step-by-step explanation:
Let X the random variable who represent the length of time it takes students to complete a statistics examination. And the distribution for x is given by:
[tex]X \sim Unif (a=40, b=60)[/tex]
And for this case we want to find the probability density function and we know that is given by:
[tex] f(x) =\frac{1}{b-a}=\frac{1}{60-40}= \frac{1}{20}, 40\leq X\leq 60[/tex]
