The u.s. bureau of labor statistics reports that 11.3% of u.s. workers belong to unions. suppose a sample of 400 u.s. workers is collected in 2014 to determine whether union efforts to organize have increased union membership at 0.025 level of significance. the sample results in a test statistic (z) of 1.31. we conclude that union membership increased in 2014. (enter 1 if the conclusion is correct. enter 0 otherwise.)

1 is the answer

Step-by-step explanation:

Given that the U.S. Bureau of Labor Statistics reports that 11.3% of U.S. workers belong to unions.

(Right tailed test for testing of a sample proportion with population proportion)

Suppose a sample of 400 U.S. workers is collected in 2014 to determine whether union efforts to organize have increased union membership at 0.025 level of significance.

Test statistic Z = 1.31

p value for this right tailed test would be 0.095

This p value is greater than 0.025

Hence at 2.5%  significance level the conclusion is correct

1 is the answer.

Similar means the pieces are in ratio

we see that 4*2=8 and 8/2=4 so each side of the larger piece divided by 2=the similar side of the smaller piece
also, any side on the smaller piece doubled yeilds the length of the similar side of the larger
so
on the smaller side, the similar side to y is 6
so 6 times 2=y=12
y=12
