Answer:
1.
Required rate = risk free rate + beta (market rate – risk free rate)
.12 = 0.0525 + 1.25(X – 0.0525)
1.25X – 0.065625 = .12 – 0.0525
1.25X = 0.0675 + 0.065625
X = .1333125/1.25
= 0.1065
Marker risk premium = market rate – risk free rate
= .1065 – 0.0525
= 0.054 (A)
2.
Beta of portfolio = (5000000/5500000)* 1.25 + (500000/5500000)* 1
= 0.90909* 1.25 + 0.090909* 1
= 1.136 + 0.090909
= 1.2273
3.
Required rate = risk free rate + beta (market rate – risk free rate)
= 0.0525 + 1.2273* 0.054
= 0.0525 + 0.06627
= .11877 or 11.88%

Answer: Matched pairs design
Explanation:
A matched pairs design is a type of study used when 2 treaments are present in an experiment. The individuals in the design can be divided into pairs using a blocking variable, and each pair can then be allocated to treatments at random. This is thus a special type of randomized block design.
In this case the blocking variable can be the various urban areas as 1968 is matched against 1972. Each city can be compared based on 2 measurements. From their each individual can be grouped into pairs and allocated to different treatments.
