Census bureau data shows that the mean household income in the area served by a shopping mall is $72,500 per year. a market research firm questions shoppers at the mall to find out whether the mean household income of mall shoppers is higher than that of the general population.

The null hypothesis states that the population mean is equal to a certain value

H°:U = $72,500

The alternative hypothesis states that the null hypothesis is false (according to the claim):

Ha:U >$72,500

Result:

H°U= $72,500

Ha:U >$72,500

it's actually a very difficult task, due to not many people can make 2 million dollars in 2 years. besides that, to the not-so-realistic ideas, you can create a business. it could be practically anything, but make it into a business that isn't that known yet, you get me? also, lets not forget about stock market. that's where all the good stuff happens. use investments at the beginning and begin to raise up your business or whatever you're going to do. as this is a very non-realistic idea, it's still worth the shot!
