Describe why beta estimates can vary from one data-base to another.
Beta estimates can vary from one data base to another
because
1. The Returns of stock vary from one time period to another. Beta
might be different if we take 10 years return and will be different
if we take 5 years returns.
2. Returns of different stocks could be different in different
stock exchanges like NYSE, Nasdaq ,etc. Hence beta could be
different.
Although these quantities vary from one type of cell to another, a cell can be 1.9 μm in diameter with a cell wall 45 nm thick. If the density (mass divided by volume) of the wall material is the same as that of pure water, what is the mass (in mg) of the cell wall, assuming the cell to be spherical and the wall to be a very thin spherical shell?
Why is the GDP so different from one another when you use a different base year to calculate the GDP? (Ex. using 2001 as base year to calculate 2019 GDP and then using 2019 as base year to calculate 2019 GDP)
What are three or more reasons why treatments for some illnesses vary from one geographic area to another? I
2. A substitution mutation is one in which one nucleotide base is changed to another Suggest ONE substitution A G mutation in the DNA that would cause the first amino acid in the "# of Eyes" gene to change from alanine (Ala) to valine (Val). In the table below, write the original.3. There is a substitution mutation in the gene for Fangs in which the first DNA base changes from guanine to thymine. The mutation results in a genetic disorder...
Discuss the different types of apneas and explain how the scoring criteria vary from one another.
why can the Rf value be used to distinguish the substances from one another? and Why is anRf value rather than the distance the spot moved used to help identify a substance by TLC?
a molecule can behave as an acid in one reaction but as a base in another reaction m. True or false? if true, provide an example molecule that exhibits this behavior
Estimates of the number of cells in the human body vary over an order of magnitude. Indeed, the precise number varies from one individual to another and depends on whether you count bacterial cells. Complete parts (a) through (c) below. a. Assume that an average cell has a diameter of 7 micrometers (7 times 10 Superscript negative 6 meter), which means it has a volume of 200 cubic micrometers. How many cells are there in a cubic centimeter? ? cells...
7.4 Profit margins and turnover ratios vary from one industry to another. What differences would you expect to find between a grocery chain and a steel company? Think particularly about the turnover ratios, the profit margin, and the DuPont equation.
use related rates. 1. One runner stands at first base and another on second base in a baseball game. At the moment a ball is hit, the runner at first base runs to second base at a speed of 18 ft/s. Simultaneously, the runner on second runs to third base at 20 ft/s. The paths between home plate, first base, second base, and third base create a square with a side length of 90 ft. a. (1 pt) How far...
