Expert Solution

Answer to Problem 2E

The density function for $U1=3Y$ is $fU1(u)=u218, −3≤u≤3$ .

Explanation of Solution

Calculation:

From the given information, the probability density function for Y is $f(y)=32y2,−1≤y≤1$ .

The distribution function for Y is,

$FY(y)=∫−1yf(t)dt=∫−1y32t2dt=32[t33]−1y=12(y3−1)$

From the given information, the random variable $U1$ is defined as $U1=3Y$ .

Consider the distribution function for $U1$ ,

$FU1(u1)=P(U1≤u)=P(3Y≤u)=P(Y≤u3)=12[(u3)3−1]$

Limits for the random variable U₁:

The range for the random variable Y is from ̶ 1 to 1 and $U1=3Y$ .

For Y= ̶ 1, the value of U₁ is ̶ 3.

For $Y=1$ , the value of U₁ is 3.

Hence, the range for the random variable U₁ is from ̶ 3 to 3.

The probability density function for $U1$ is,

$fU1(u)=F′U1(u)=ddu(12[(u3)3−1])=12×3(u3)2×13=u218, −3≤u≤3$

Consider the distribution function for $U2$ ,

$FU2(u)=P(U2≤u)=P(3−Y≤u)=P(−Y≤u−3)=P(Y>3−u)$

$=1−F(3−u)=1−12[(3−u)3−1]=−12(3−u)3+32$

Limits for the random variable U₂:

The range for the random variable Y is from ̶ 1 to 1 and $U2=3−Y$ .

For Y= ̶ 1, the value of U₂ is 4.

For $Y=1$ , the value of U₂ is 2.

Hence, the range for the random variable U₂ is from 2 to 4.

The probability density function for $U2$ is,

$fU2(u)=F′U2(u)=ddu(−12(3−u)3+32)=32×(3−u)2,2≤u≤4$

Thus, the density function for $U2=3−Y$ is $fU2(u)=32×(3−u)2,2≤u≤4$ .

Answer to Problem 2E

The density function for $U3=Y2$ is $fU3(u)=32u,0≤u≤1$ .

Explanation of Solution

Calculation:

From the given information, $U3=Y2$ .

Consider the distribution function for $U3$ ,

$FU3(u)=P(U3≤u)=P(Y2≤u)=P(−u≤Y≤u)=F(u)−F(−u)$

$=12((u)3−1)−12((−u)3−1)=12(u)3−12+12(u)3+12=u32$

The probability density function for $U3$ is,

$fU3(u)=F′U3(u)=ddu(u32)=32×(u12),0≤u≤1$

Thus, the density function for $U3=Y2$ is $fU3(u)=32u,0≤u≤1$ .

$FU3(u)=P(U3≤u)=P(Y2≤u)=P(−u≤Y≤u)=F(u)−F(−u)$

$=12((u)3−1)−12((−u)3−1)=12(u)3−12+12(u)3+12=u32$

The probability density function for $U3$ is,

$fU3(u)=F′U3(u)=ddu(u32)=32×(u12),0≤u≤1$

Thus, the density function for $U3=Y2$ is $fU3(u)=32u,0≤u≤1$ .

Answer 26

Explanation of Solution

Calculation:

From the given information, $U3=Y2$ .

Consider the distribution function for $U3$ ,

$FU3(u)=P(U3≤u)=P(Y2≤u)=P(−u≤Y≤u)=F(u)−F(−u)$

$=12((u)3−1)−12((−u)3−1)=12(u)3−12+12(u)3+12=u32$

The probability density function for $U3$ is,

$fU3(u)=F′U3(u)=ddu(u32)=32×(u12),0≤u≤1$

Thus, the density function for $U3=Y2$ is $fU3(u)=32u,0≤u≤1$ .
