A sociologist is interested in the relation between x = number of job changes and y = annual salary (in thousands of dollars) for people living in the Nashville area. A random sample of 10 people employed in Nashville provided the following information. x (number of job changes) 5 3 6 6 1 5 9 10 10 3 y (Salary in $1000) 36 37 34 32 32 38 43 37 40 33 (d) If someone had x = 2 job changes, what does the least-squares line predict for y, the annual salary? (Round your answer to two decimal places.) thousand dollars thousand dollars
Contingency Table
A contingency table can be defined as the visual representation of the relationship between two or more categorical variables that can be evaluated and registered. It is a categorical version of the scatterplot, which is used to investigate the linear relationship between two variables. A contingency table is indeed a type of frequency distribution table that displays two variables at the same time.
Binomial Distribution
Binomial is an algebraic expression of the sum or the difference of two terms. Before knowing about binomial distribution, we must know about the binomial theorem.
A sociologist is interested in the relation between x = number of job changes and y = annual salary (in thousands of dollars) for people living in the Nashville area. A random sample of 10 people employed in Nashville provided the following information.
x (number of job changes) | 5 | 3 | 6 | 6 | 1 | 5 | 9 | 10 | 10 | 3 |
y (Salary in $1000) | 36 | 37 | 34 | 32 | 32 | 38 | 43 | 37 | 40 | 33 |
(d) If someone had x = 2 job changes, what does the least-squares line predict for y, the annual salary? (Round your answer to two decimal places.)
