In addition, 88% of companies say that there is a shortage of qualified job candidates. Suppose 16 workers are randomly selected and asked if they would change jobs for "slightly higher pay."

Robert Zoellick had a very interesting column in the Wall Street
Journal called “Leave No Country Behind in the Post-Covid
recovery”
Robert Zoellick is someone that I trust: he is a former World
Bank President, former U.S. Trade Representative, and former Deputy
Secretary of State.
Here are 2 sentences that I thought were important:
• “The U.S. should recognize that its healthy recovery--from
both disease and economic disaster--depends on revivals elsewhere.”
That is, we’re all in this together.
• “Countries...

QUESTION 1
The Wall Street Journal reported that the average
amount of time that a French person spends eating lunch at a
restaurant is 22 minutes. Perform a hypothesis test to determine if
a difference exists between the average time an American spends
eating lunch when compared to a person from France. The following
data represents the time, in minutes, that random French and
American diners spent at lunch. Assume that the population
variances are unequal.

3) The Wall Street Journal reported that recipients of a
bachelor degree with major in business receive average starting
salaries of $55,000 in 2017, with a standard deviation of $4,000. A
sample of 100 salaries from business majors collected in 2018 shows
a mean starting salary of $ $54,000. You are hired as a
statistician to investigate whether there are salary differences
for business majors in 2018 with respect to 2017. Allow for 5%
error on a two tail test....

2 a) The Wall Street Journal reported in January 2018 that the
makers of many household goods have increased the price of
household/personal care products by 2.9% from prices in the
previous year. If the elasticity of demand were 0.48, then we can
predict that the quantity of household products should have ______
( increased ;decreased ) by _________. Show calculation/method
here:
b). For this question, write the correct elasticity measure
below the product you think it matches best then...

As reported in the Wall Street Journal in November 2016, the 11
countries that make up the oil cartel OPEC agreed to each cut their
oil production over 2017 by 2% in an effort to raise the price of
oil and increase their profits (since the demand for oil is
inelastic). Let’s use a simplified one-off game with only two
countries (Iran and Saudi Arabia) to analyze the strategic
interaction between the countries and the likely impact on oil
revenues...

The Wall Street Journal reported that 33% of taxpayers with adjusted gross incomes between $30,000 and $60,000 itemized deductions on their federal income tax return. The mean amount of deductions for this population of taxpayers was $15,071. Assume that the standard deviation is 82,790. Use 2-table. a. What is the probability that a sample of taxpayers from this income group who have itemized deductions will show a sample mean within $200 of the population mean for each of the following sample...
