Question

Some have good that throwing darts at the stock pages to decide which companies to invest in could be a success stock picking strategy Suppese a researcher decides to test this theory and randomly chooses 300 companies to invest in het 1 year 199 of the companies were considered winners that is, they outperformed other companies in the same investment class To assess whether the dartpicking strategy resulted in a majority of winners, the researcher testedp=05 versus Hyp>05 and obtained a P value of 0.1493. Explain what this P-value means and wille a conclusion for the researcher (Assume is 0.1 or less) Choose the correct explanation below. O A About 15 in 100 samples will give a sample proportion as high or higher than the one obtained the population proportion really s05 OB. About 150 in 300 samples will give a sample proportion as high or higher than the one obtained the population proportion really is 05. OC About 1 in 300 samples will give a sample proportion as high or higher than the one obtained the population proportion really is greater than 05 OD. About 15 in 100 ans will give a sample proportion as high or higher than the one obtained the population proportion really is greater than 05 Choose the correct conclusion below. OA Became the value is large, do not reject the rol hypothesis. There is not sufficient evidence to conclude that the dail picking strategy resulted in a majority of Winners OB. Became the value is wat do not reject the rol hypothesis. There is not sufficient evidence to conclude that the dart picking strategy resulted in a majority of Winners OC. Because the value is large. reject the null hypothesis There is sufficient evidence to conclude that the dart picking wategy rested in a majority of winners OD. Because the value is smal, reject the rulhypothesis. There is sufficient evidence to conclude that the dart picking strategy resulted in a majority of winners Click to select your awer

Answer 1

Answer:

a) P - value is 15 so about 15 out of 100 samples will given sample proportion as high or higher than the one obtained if population proportion is 0.5

Option A is correct.

b) From the given Information,

p – value = 0.1493

Because the p-value is large, do not reject the null hypothesis. There is not sufficient evidence to conclude that dart-picking strategy resulted in a majority of winners.

Option A is correct.
