Question

The U.S. Bureau of Labor Statistics reports that 11.3% of U.S. workers belonged to labor unions in 2013. Suppose a sample of 400 U.S. workers is collected in 2018 to determine whether union efforts to organize have increased union membership.

a. Formulate the hypotheses that can be used to determine whether union membership increased in 2018 from 2013. (5 pts. Put this answer in Blank 1).

b. If the sample results who that 52 of the workers belonged to unions, what is p ̅ ? (5 pts. Put this answer in Blank 2).

c. What is the value of the test statistic? (5 pts. Put this answer in Blank 3).

d. At a=0.05, what is your conclusion? (5 pts. Put this answer in Blank 4).

Answer #1

The consumer price index is reported monthly by the u.s. bureau
of labor statistics. It reports the change in prices for a market
basket of goods from one period to another. The index for 2003 was
237.1. By 2014, it increased to 278.100.
what was the geometric mean annual increase for the period?
(Round your answer to 2 decimal places.)

According to the U.S. Bureau of Labor Statistics, the average
weekly earnings of a production worker in manufacturing in the
United States as of October 2014 was $827.27. Suppose a labor
researcher wants to test to determine whether this figure is still
accurate today. The researcher randomly selects 54 production
workers from across the United States and obtains a representative
earnings statement for one week from each worker. The resulting
sample average is $843.56. Assuming a population standard deviation
of...

The U.S. Bureau of Labor Statistics released hourly wage figures
for various countries for workers in the manufacturing sector. The
hourly wage was $30.67 for Switzerland, $20.20 for Japan, and
$23.82 for the U.S. Assume that in all three countries, the
standard deviation of hourly labor rates is $3.00.
a. Suppose 42 manufacturing workers are selected
randomly from across Switzerland and asked what their hourly wage
is. What is the probability that the sample average will be between
$30.00 and...

According to the U.S. Bureau of Labor Statistics, the average
weekly earnings of a production worker in July 2011 were $657.49.
Suppose a labor researcher wants to test to determine whether this
figure is still accurate today. The researcher randomly selects 54
production workers from across the United States and obtains a
representative earnings statement for one week from each. The
resulting sample average is $672.41. Assuming a population standard
deviation of $63.90 and a 5% level of significance, determine...
