Answer:
Step-by-step explanation:
Given: 76,45,64,80,92
Required: Determine the standard deviation
We start by calculating the mean
Where x-> 76,45,64,80,92 and n = 5
Subtract Mean (71.4) from each of the given data
Determine the absolute value of the above result
Square Individual Result
Calculate the mean of the above result to give the variance
Hence, Variance = 255.298
Standard Deviation is calculated by 
Answer:
The given statement is true.
Step-by-step explanation:
Regression Analysis:
- Regression analysis is a technique that help us to find or define a relationship between a dependent and an independent variable.
- It helps us to predict the dependent variables with the help of independent variables.
- Various techniques are used for the prediction of independent variable.
- It is a type of predictive statistical technique and helps us to find whether there is a significant relationship between the dependent and the independent variable.
Correlation analysis:
- Correlation is a technique that help us to find or define a relationship between two variables.
- It is a measure of linear relationship between two quantities.
- It is not necessary that the that out of the two variable one needs to be dependent and the other to be independent.
- Correlation can be positive, negative or zero correlation.
Thus, the given statement is true.
