Answer #1

The confidence interval for a population parameter gives the range in which there is a C probability that the true population parameter lies in that range. Therefore confidence interval is not the correct option here.

Scatter diagram is a graph plot that shows the relationship between 2 variables, that is one variable on x axis while the other one on the y axis. Therefore scatter diagram is also not correct here.

Regression Analysis is a technique to form a linear relationship between the 2 variables. Therefore regression analysis is not the correct answer here.

The descriptive statistics shows the summary chracteristics of the data like mean, number of values and other such information. Therefore descriptive statistics is the correct option here.
