Answer:
a. count of observations that meet a condition (counts), total number of observations (nobs), Hypothesized value of population proportion (value).
Explanation:
In other to use the proportion_ztest method, the need to make import from the statsmodel module ; statsmodels.stats.proportion.proportions_ztest ; this will allow use use the Z test for proportion and once this method is called it will require the following arguments (count, nobs, value=None, alternative='two-sided', prop_var=False)
Where;
nobs = number of observations
count = number of successes in the nobs trial or the number of successes for each independent sample.
Value = hypothesized value of the population proportion.
Answer:
a) Global
Explanation:
The scope of a variable declared outside of any function is Global.
Let us consider an example:
int g;
int add(int a,int b){
return a+b;
}
int subtract(int a,int b){
return a-b;
}
Here the variable g is defined outside any function and is accessible anywhere within the program. This is a global variable.
Variables defined within each function - a,b on the other hand have a local scope are are visible only within their respective function bodies.
Answer:
The code will display the following on the screen:-
2
0
2
Explanation:
The output is like this because x{2} assigns the value 2 to the integer x.First the value of x is printed on the screen that is 2 and that newline is used to go to the next line.After that function is called doSomething with x passed as the argument. doSomething function assigns the value zero to the variable passed and prints it on the screen.So the next line is 0.Since x is passed by value so no changes will appear in the original argument.Hence the last line printed is 2.
Answer:
3% inflation rise. No correct cpi option
Explanation:
Consumer Price Index(CPI) is calculated by the Bureau of Economic Analysis and Statistics of a country monthly and annually.
Consumer Price Index(CPI) is used for measuring the changes in the price level of consumer goods and services purchased by households.
Calculating the consumer price index; price in 1964= $1.25, today price= $5.0.
Therefore, consumer price index= Price in today- price in 1964÷ price in 1964,.
Consumer Price index(CPI)= $(5-1.25)/1.25 = 3.75/1.25 = 3 Percent price inflation rise.
For the first cpi; 112-80/80= 0.4 percent( not equal to the 3 Percent inflation rise).
For the second cpi: 141.6-60/60= 1.36 Percent inflation rise(not equal to the 3 Percent inflation rise).
For the third CPI: 126.4-75/75 =0.68 percent inflation rise[not equal to the 3 Percent inflation rise].
For the third CPI: 108.5-90/90=0.21 percent inflation rise(not equal to 3 Percent inflation rise)
Therefore, none of the options are right.
