Answer:
A skilled broker will be right at 60% of time compared to 50%
Explanation:
Solution
Given that:
Now,
Let X be represented as = number of correct predictions/outcomes
X foll binomial distribution with n = 3 and p = 0.5 for broker who use a toss coin
Thus,
P(X = 3) = p^3 = 0.5^3 which gives us = 0.125
So,
For a skilled broker, Y goes with the binomial distribution with n = 3 and p is = 0.6
Then,
P(Y = 3) = 0.6^3 = 0.216
We can therefore conclude who is skilled broker by making large number of observations
Hence, we say that a skilled broker will be correct 60% of time compared to 50%

Answer:
Yes
Explanation:
From the given output
The Probability of getting 13 or more passed
when the reliability = 0.35. can be calculated as follows
=0.0258+0.0109+0.0039+.0012+0.0004 = 0.0422 ≈ 4.2%
Since the probability is less than the 5% level we will therefore reject the Null hypothesis
answer : YES
Answer:
d. Both the longer term and the higher risk would tend to make the interest rate higher on the bond issued by Knight.
Explanation:
Both the longer term and the higher risk would tend to make the interest rate higher on the bond issued by Knight because this bond is risky and uncertain.
This means the company would not want to run at a loss
