Answer:
The solution code is written in R script.
- #string variable
- character_str<- "Hello World"
- #logical variable
- logic <- a > b
- #Missing value
- myVec <-c(1, 2, 3, NA)
- #Use class to check data type
- class(character_str)
- class(logic)
- class(myVec)
Explanation:
A string variable is a variable that hold a string (the letters enclosed within quotation marks) (Line 2)
A logical variable is a variable that hold a logical value (either True or False). The logical value is created by comparing two variables (Line 5).
In R, missing value is an unknown value which is represented by NA symbol (Line 8).
We can use in-built method <em>class </em> to check for the variable type in R (Line 11-13). For example, the output of <em>class(character_str)</em> is "<em>character</em>"
Explanation:
On October 31, around twelve o'clock at night, the lights were dull. It was Siberian cold and I was walking painfully under the whitish lighting of a lamppost and the retro neon lights of a convenience store in a neighborhood that was buzzing when I went to buy meat. buildings, grayish in this half-light, crumbled under the weight of sleep, while the neighborhood was still open. Its decoration was particularly macabre in tone: synthetic but very sticky spider webs adorned the porches of the terraces, pumpkin ornaments are exhibited like works of art, ... Some pushed the macabre by hanging mannequins made up in corpses. At the entrance to the neighborhood, I found the body of its owner stabbed. Frozen in place, I wondered what else awaits me. My heart was pounding, feeling a shiver of anguish. When I was removing the phone from my pocket to call my police friends, my hands were clenched in fear. An investigation was carried out to find out the causes of death. Also, I went with them so they take my words. Hopefully the murderer will be arrested to put an end to this sybilinous crime.

Answer: E. Never
geometric average return can NEVER exceed the arithmetic average return for a given set of returns
Explanation:
The arithmetic average return is always higher than the other average return measure called the geometric average return. The arithmetic return ignores the compounding effect and order of returns and it is misleading when the investment returns are volatile.
Arithmetic returns are the everyday calculation of the average. You take the series of returns (in this case, annual figures), add them up, and then divide the total by the number of returns in the series. Geometric returns (also called compound returns) involve slightly more complicated maths.
