Answer:
lower range 33.822 years
upper range 38.178 years
Explanation:
step 1:
48 -1 = 47
step 2:
(1 - 95%) / 2 = 0.025
step 3:
we look at the T distribution table for degrees of freedom (df) = 47, and α = 0.025; = 2.0117
step 4:
divide sample standard deviation by square root of sample size
7.5 years / √48 = 7.5 / 6.9282 = 1.0825
step 5:
multiply results from step 3 and 4
2.0117 x 1.0825 = 2.178
step 6:
for the lower range, subtract step 5 from sample mean
36 - 2.178 = 33.822
step 7: for the upper range, add step 5 with sample mean
36 + 2.178 = 38.178

Answer: a. 11.5%
Explanation:
Fad followers are those investors who follow a trend when it emerges and as such their betas will be less than that of informed traders because the informed traders would have acted first.
Using the Capital Asset Pricing Model to calculate expected return.
Er = Rf + b( Rm - Rf)
Er = Expected return
Rf = Risk Free Rate
b = Beta
Rm = Market Return.
The Expected Return for the Informed Investors is,
= 4% + 1.4 ( 10% - 4%)
= 4% + 1.4 ( 6%)
= 12.4%
With the Fad followed expected to have a lower beta and therefore a lower expected return than the Informed Investors, the only suitable option is the 11.5%.
Answer:
<h2>Because firms in a perfectly competitive market does not have any price making ability or market power,they are not able to engage in any price discrimination.Hence,the correct answer is the last option or True,because perfectly competitive firms have no market power.</h2>
Explanation:
In Microeconomics,perfectly competitive markets are characterized by many buyers and sellers in which the sellers and firms usually sell homogeneous or identical products.Now,as there are many firms in the market and no barriers to entry for new firms into the market,the market competition or rivalry is high and hence,no single firm has the ability to determine and manipulate the market price according to their own economic advantage because if any firm tries to do so,it will loose significant market share as most customers would move to other sellers/firms charging lower price or regular market price.Therefore,the market price is fixed in the perfectly competitive market as the firms do not have price making or market power.Consequently,they are not able to charge different prices to different customers according to their maximum willingness to pay or differences in price preferences.
Answer:
The correct answer is:
Ratio Scale
Explanation:
A ration scale of measurement is one that has equal units of measurement, and has an absolute value of zero. Measurements below the zero point on the scale is not possible. for example in the measurement of height in meters, the lowest measurement possible is 0 meter, a measurement of - 1 meter will make no mathematical sense. In this example, if a score of 60 is said to have twice as much attributes than a score of 30, it means that this attributes are measured from a reference zero point, because truly, 60 is twice as much as 30, from a zero point on a scale.
The other scales of measurements include;
nominal scale of measurement; which contains mainly categorical data and is mainly used in form of tags rather than showing magnitude or intervals. Example is grouping a group of adults into married, divorced or single.
Ordinal scale; this scale shows hierarchical series or ordered series, but does not show intervals between the elements. example is in classifying the positions of participants in a race as first, second or third etc. There is an ordering, as the first position is on top of the list, but it will now make sense to say the distance between the attribute of first to third position is the same as the distance between the attributes between third and fifth position, as there is no scale.
Interval scale; this scale of measurement does not have a limit zero value which represents the least possible point on a scale, but the intervals between different units on the scale can be compared logically. Example is the measurement of temperature using the Fahrenheit scale, where the temperature can go as low as - 20°F, below the zero point, and a distance of 3°F to 5°F can be said to be equal to a distance of 10°F to 12°F.
