Answer:
Probability, P(n) = 3/8
Explanation: Let standard delivery be S and express delivery be E.
I) When the parcels were sent:
S(n) = 75/100 and E(n) = 25/100
II) When the parcels arrived:
S(n)← = 80/100 and E(n)← = 95/100
The probability a record of a parcel delivery is chosen, P(n) = S(n)*E(n) + E(n)*S(n) = 75/100*25/100 + 25/100*75/100
P(n) = 3/16 + 3/16 = 6/16
∴ P(n) = 3/8
Answer:
A)0.67
Explanation:
Coefficient of variation can be regarded as the method that is usually devices in the assessment of the total risk per unit of return in a particular investment.
To calculate the investment's coefficient of variation, we use the expresion below
Coefficient of variation = standard deviation/expected return.
Given:
expected return = 15%
standard deviation = 10%.
Coefficient of variation =10/15
= 0.67
Hence, the investment's coefficient of variation is 0.67
Answer:
a framing bias
Explanation:
Framing bias occurs when a person chooses an option based on whether it was presented in positive or negative terms. There is tendency to avoid risk on positive presentation, and seek risk on negative presentation. It is a form of cognitive bias.
On this scenario Bayram is to choose between two investments. One was said to have 30% chance of success and the other a 70% chance of failure.
Although both investments have the same risk and benefit Bayram chose the one that was presented as 30% chance of success.
This phenomenon of choosing based on positive presentation is called framing bias.
