Let p1 be the proportion of American adults that were cigarette smokers in 2001
Let p2 be the proportion of American adults that were cigarette smokers in 1983

h0= p1= p2 (The null hypothesis assumes that there is no difference in the proportion of American adults that were cigarette smokers in 2001 and 1983. 

ha= p1 < p2 (The alternative hypothesis assumes that the proportion of American adults that were cigarette smokers in 1983 is higher than those in 2001.)

If we're assuming an average user with no special requirements for programming or other specialised tasks then I'd recommend Windows 10.

Windows 10 is the most popular OS (Operating System) and is widely supported by the community of you run into trouble.

You can find a liscenced copy from their website, which you may need to change to your locale and most computer shops will sell copies too, including online companies like Amazon, but if you're unsure then Microsoft is the best bet.

Wage contracts, efficiency wages, and the minimum wage are explanations for why:
hjlf

Answer:

B. Wages tend to be inflexible downward

Explanation:

Wages are flexible if they react to changes in demand and supply. Profitability determines demand and supply level for wages.  Flexibility in wages means that If the economy is performing well, companies should compensate their employees better.

Wage inflexibility implies that wages will not respond to changes in demand and supply. Wages do not rise or fall if the marginal productivity of labor increases or decreases.  Wage contracts are agreements that tend to set compensation for workers regardless of their output.  Minimum wage is a regulatory requirement that demands workers not to be paid below a set rate. Wage efficiency recommends higher than market rate compensation to motivate productivity.

The three factors do not advocate for wages to be pegged on productivity.
