A: Given information: The random variable is X. The mean of X is μ. The variance of X is σ2. The term a…

Q: Assume a continuous random variable X has a continuous uniform distribution between 35 and 48. Find…

A: given data  x is uniform distribution between 35 and 48 P(38&lt;x&lt;50) = ?

Q: Assume that the cumulative distribution function of the random variable X is (image): Determine the…

A: i) Since, -2&lt;1.8&lt;2 , so F(1.8) follows 0.25x+0.5 P(X &lt; 1.8)=F(1.8)=0.25(1.8)+0.5=0.95
