(a) Explanation Given Information: The relative frequency table for X the number of checkout lanes for a randomly selected supermarket is, x 1 2 3 4 5 6 7 8 9 10 P ( X = x ) 0.01 0.04 0.04 0.08 0.10 0.15 0.25 0.20 0.08 0.05 Formula used: Expected value is computed by using the formula, E ( X ) = ∑ i = 1 n x i ⋅ P ( X = x i ) Where, P ( X = x i ) is the probability value for X = x i . The probability using the formula, P ( X = x ) = Number of favorable outcomes Total number of outcomes Calculation: Consider the probability distribution, x 1 2 3 4 5 6 7 8 9 10 P ( X = x ) 0.01 0.04 0.04 0.08 0.10 0.15 0.25 0.20 0.08 0.05 The value of x ⋅ P ( X = x ) for X = 1 , 1 ⋅ P ( X = 1 ) = 1 ⋅ ( 0 (b) To determine Which is larger P ( X < μ ) or P ( X > μ ) and interpret the result from the following relative frequency table: x 1 2 3 4 5 6 7 8 9 10 P ( X = x ) 0.01 0.04 0.04 0.08 0.10 0.15 0.25 0.20 0.08 0.05

Correlation

Correlation defines a relationship between two independent variables. It tells the degree to which variables move in relation to each other. When two sets of data are related to each other, there is a correlation between them.

Linear Correlation

A correlation is used to determine the relationships between numerical and categorical variables. In other words, it is an indicator of how things are connected to one another. The correlation analysis is the study of how variables are related.

Regression Analysis

Regression analysis is a statistical method in which it estimates the relationship between a dependent variable and one or more independent variable. In simple terms dependent variable is called as outcome variable and independent variable is called as p…
