Some have argued that throwing darts at the stock pages to decide which companies to invest in could be a successfulstock-picking strategy. Suppose a researcher decides to test this theory and randomly chooses 50 companies to invest in. After 1year, 26 of the companies were consideredwinners; thatis, they outperformed other companies in the same investment class.

To assess whether thedart-picking strategy resulted in a majority ofwinners, the researcher tested H0: p=0.5 versus H1: p>0.5 and obtained aP-value of 0.3886.

Choose the correct conclusion below.

A.

Because this probability is notsmall, do not reject the null hypothesis. There is not sufficient evidence to conclude that thedart-picking strategy resulted in a majority of winners.

B.

Because this probability issmall, do not reject the null hypothesis. There is not sufficient evidence to conclude that thedart-picking strategy resulted in a majority of winners.

C.

Because this probability issmall, reject the null hypothesis. There is sufficient evidence to conclude that thedart-picking strategy resulted in a majority of winners.
