"Let fx(z) be the probability density function of the random variable X _3 <x < 4 f(z) otherwise_ Determine Fx(0.9) [The answer should be & number rounded to five decimal places, don't use symbols such as %]"
Added by M-Nica M.
Step 1
From the given information, we know that: - fx(z) = 0 for z < 3 - fx(z) = f(z) for 3 ≤ z ≤ 4 - fx(z) = 0 for z > 4 Since fx(z) is a probability density function, it must integrate to 1 over the entire range of X. Therefore, we can find f(z) as follows: ∫3^4 Show more…
