9.61 according to the u. s. department of labor, 12.3% of the u. s. workforce was unionized in 2009. this percentage has declined steadily since the end of world war ii, when more than a third of u. s. workers belonged to a union. suppose the department would like to test the hypothesis that the proportion of union workers decreased in 2014 by randomly sampling 160 employees. (a) explain in your own words how type i and type il errors can occur in this hypothesis test (b) using a 0.05, calculate the probability of a type ll error if the actual proportion of unionized employees in the workforce is 10%. (c) using a 0.05, calculate the probability of a type il error if the actual proportion of unionized employees in the workforce is 5%.

step-by-step explanation:

answer:

it is general formula that is used to write value to its excet position

a11 a12 a13

a21 a22 a23

it is the example of order 2 by 3 matrix in this

a11 means value occur in 1 st row 1st column

a12 means value occurs in 1st row 2nd column

a13 means value occur in 1st row and 3rd column

a21 means value occurs in 2nd row and 1st column

a22 means value occurs in 2nd row and in 2nd column

a23 means value occurs in 2nd row and in 3rd column
