A researcher is running an experiment on the effectiveness of
three different energy drinks. She randomly selects 150 individuals

which consumes a different energy drink.
1. The research/alternative hypothesis for this test is that at
least one of the three groups will be different. True or False?
The statistical results of the test are as follows: F(2, 147) =
2.24, p > .05.
2. In the above results, degrees...

An investor has the opportunity to buy one of four different
stocks. Each stock is currently selling for $50 per
share, and the investor will choose one of the stocks and purchase
20 shares of one of the stocks and sell them one year
later. (Hence, the investor is making an initial
investment of 20*$50=$1000.) When buying the stock, the investor
doesn’t know whether or not there will be a recession when she goes
to sell the 20 shares of stock in...
