Choose the correct conclusion below.

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 100 companies to invest in. After 1 year, 52 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 Ho: p= 0.5 versus
H p>0.5 and obtained a P-value of 0.3446. Explain what this P-value means and write a conclusion for the researcher. (Assume a is 0.1 or less.)
Choose the correct explanation below.
O A. About 52 in 100 samples will give a sample proportion as high or higher than the one obtained if the population proportion really is greater than 0.5.
O B. About 52 in 100 samples will give a sample proportion as high or higher than the one obtained if the population proportion really is 0.5.
O C. About 34 in 100 samples will give a sample proportion as high or higher than the one obtained if the population proportion really is greater than 0.5.
O D. About 34 in 100 samples will give a sample proportion as high or higher than the one obtained if the population proportion really is 0.5.
Choose the correct conclusion below.
O A. Because the P-value is small, do not reject the null hypothesis. There is not sufficient evidence to conclude that the dart-picking strategy resulted in a
