1. In the world of social media, understanding the factors that contribute to the number of likes on a post is crucial for content creators. Let’s consider a scenario where you want to predict the number of likes on Instagram posts based on two variables: the number of followers and the length of the caption.

Post	Likes	Followers	Caption Length
1	120	5000	150
2	85	5500	180
3	100	6000	200
4	110	4500	160
5	95	7000	140
6	130	5200	170
7	75	5800	190
8	115	6300	150
9	80	4800	180
10	150	7500	160
11	105	5100	130
12	90	6700	170
13	125	5900	200
14	70	6800	150
15	140	5400	180
16	95	7200	160

2. Samantha Patel, employed as an analyst in a renowned technology firm, is contemplating investing her savings in the stock market. Recommendations from her friends, who possess expertise in stock market investments, led her to consider investing in ‘TechGen’ and ‘InnovateCorp’ shares. An economist friend, Rahul Kapoor, has outlined four different scenarios regarding potential returns on Samantha’s investments. The payoff figures for one unit of share in INR for each scenario are as follows:

Payoff (Profit within one month on one unit of share in INR)	Scenario 1 (s1)	Scenario 2 (s2)	Scenario 3 (s3)	Scenario 4 (s4)
TechGen	48	35	22	15
InnovateCorp	32	40	45	53

 

1. Set up the opportunity loss table based on the provided payoff figures.
2. Create a decision tree illustrating the decision-making process for Samantha’s investment. You may use any software for making the tree diagram, but a handwritten snapshot will be unacceptable.

In making of this tree show the payoff values given above only.

• According to Rahul Kapoor’s latest research, he has assigned the following probabilities to the four scenarios (states of nature):

P(S1) = 0.3

P(S2) = 0.4

P(S3) = 0.2

P(S4) = 0.1

Determine the Expected Monetary Value (EMV) decision based on the

probabilities assigned by Rahul.                                                               (10 Marks)
