Chapter 12, Problem 1PS

Determine the critical value of χ 2 with 1 degree of freedom in each of the following circumstances:

a . α = 0.01 b . α = 0.005 c . α = 0.10

a.

Expert Solution
Check Mark
To determine

Determine the critical value of χ2 , if α=0.01 .

Answer to Problem 1PS

The critical value is 6.635.

Explanation of Solution

The critical value of χ2 from χ2 -table which is given in table E.4 at degree of freedom 1 and upper tail value 0.01, if α=0.01 is 6.635.

Therefore, the required critical value is 6.635.

b.

Expert Solution
Check Mark
To determine

Determine the critical value of χ2, if α=0.005 .

Answer to Problem 1PS

The critical value is 7.879.

Explanation of Solution

The critical value of χ2 from χ2 -table which is given in table E.4 at degree of freedom 1 and upper tail value 0.005 is 7.879.

Therefore, the required critical value is 7.879.

c.

Expert Solution

You have been hired as an intern to run analyses on the data and report the results back to Sarah; the five questions that Sarah needs you to address are given below. please do it step by step   Does there appear to be a positive or negative relationship between price and screen size? Use a scatter plot to examine the relationship. Determine and interpret the correlation coefficient between the two variables. In your interpretation, discuss the direction of the relationship (positive, negative, or zero relationship). Also discuss the strength of the relationship. Estimate the relationship between screen size and price using a simple linear regression model and interpret the estimated coefficients. (In your interpretation, tell the dollar amount by which price will change for each unit of increase in screen size). Include the manufacturer dummy variable (Samsung=1, 0 otherwise) and estimate the relationship between screen size, price and manufacturer dummy as a multiple linear…
