The U.S. Bureau of Labor Statistics reports that 11.3% of U.S. workers belong to unions (BLS website, January 2014). Suppose a sample of 400 U.S. workers is collected in 2014 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 2014.H 0: p H a: p
b. If the sample results show that 52 of the workers belonged to unions, what is the p-value for your hypothesis test (to 4 decimals)?
A company manages an electronic equipment store and has ordered
200200
LCD TVs for a special sale. The list price for each TV is
$200200
with a trade discount series of
6 divided by 10 divided by 2.6/10/2.
Find the net price of the order by using the net decimal equivalent.
