A 2011 survey, by the Bureau of Labor Statistics, reported that 91% of Americans have
paid leave. In January 2012, a random survey of 1000 workers showed that 89% had
paid leave.
The resulting p-value is .0271; thus, the null hypothesis is rejected. It is concluded that
there has been a decrease in the proportion of people, who have paid leave from 2011 to
January 2012.
What type of error is possible in this situation?
A. type I
B. type II
C. neither
D. both

Arrange the steps to solve this system of linear equations in the correct sequence. x + y = -2 2x – 3y = -9 tiles subtract 3x + 3y = -6 (obtained in step 1) from 2x – 3y = -9 (given) to solve for x. substitute the value of x in the first equation (x + y = -2) to get y = 1. the solution for the system of equations is (-3, 1). x = -15 the solution for the system of equations is (-15, 13). add 3x + 3y = -6 (obtained in step 1) to 2x – 3y = -9 (given), and solve for x. x = -3 substitute the value of x in the first equation (x + y = -2) to get y = 13. multiply the first equation by 3: 3(x + y) = 3(-2) 3x + 3y = -6.
