Question 4
Suppose x is a continuous random variable with the following probability density function (pdf):
CCCx%100==59x,E[x]P(0.2. Assign your answer
to the variable ans
In[]: # your code here
fail() # No Answer - remove if you provide an answer
In[]: ## check whether the 2nd & 3rd dec. digits are 59
if(testthat (desc="", code ={
expectequal ((floor(ans*103)%100==59), TRUE)
}) TRUE) stop("Sorry, your answer is incorrect.")
In[]: # test whether the answer is correct (hidden test)
Part c)
Determine the expected value ofx,E[x]. Assign your answer to the variable EX
In[]: # your code here
fail() # No Answer - remove if you provide an answerf(x)={[C(x-x3),0
where Cis a constant.
Part a)
Determine the value of the constant, C. Assign your answer to the variable C(uppercase)
In[]: # your code here
fail() # No Answer - remove if you provide an answer
In[19]: # test whether the answer is correct (hidden test)
Part b)
Determine the (exact) probability that xis between 0.2 and 0.5. That is, determine P(0.2. Assign your answer
to the variable ans
In[]: # your code here
fail() # No Answer - remove if you provide an answer
In[]: ## check whether the 2nd & 3rd dec. digits are 59
if(testthat (desc="", code ={
expectequal ((floor(ans*103)%100==59), TRUE)
}) TRUE) stop("Sorry, your answer is incorrect.")
In[]: # test whether the answer is correct (hidden test)
Part c)
Determine the expected value ofx,E[x]. Assign your answer to the variable EX
In[]: # your code here
fail() # No Answer - remove if you provide an answer
