Two competitive investment fund managers devised a plan
to determine which one is better at picking stocks. They
hired a statistician to randomly select some stocks from
each manager's portfolio and to compare the proportions of
these stocks that are valued higher than they were 6 months
earlier. Her analysis revealed that 66% of the stocks picked
by manager #1 had increased in value while 60% of the
stocks picked by manager #2 had increased in value. Her
p-value for a two tailed test was 0.3500. At a significance
level of 0.05, what should she conclude?
There is insufficient evidence to conclude that the
two fund managers differ in their ability to pick
stocks.
