Some have argued that throwing darts at the stock pages to decide which companies to invest in could be a successful stock-picking strategy. suppose a researcher decides to test this theory and randomly chooses 50 companies to invest in. after 1 year, 26 of the companies were considered winners; that is, they outperformed other companies in the same investment class. to assess whether the dart-picking strategy resulted in a majority of winners, the researcher tested upper h 0: pequals0.5 versus upper h 1: pgreater than0.5 and obtained a p-value of 0.3886. explain what this p-value means and write a conclusion for the researcher. (assume alpha is 0.1 or less.)
