Mark recently invested equal amounts in five stocks to form an investment portfolio which has a beta equal to 1.7. Mark is considering selling the riskiest stock in the portfolio, which has a beta coefficient equal to 2.5, and replacing it with another stock. If Mark replaces the stock with a beta coefficient equal to 2.5 with a stock with a beta coefficient equal to 1.0, what will be the new beta of his investment portfolio?

A cell phone manufacturer claims that the population mean battery life of its flagship smartphone model, the Black Bear, is greater than the population mean battery life of the largest competitor, the Grizzly. A consumer advocacy publication tests this claim by purchasing a random sample of Black Bear smartphones and a random sample of Grizzly smartphones. Members of the publication charged each smartphone to full capacity and then had the smartphones play back the same videos until the batteries were completely depleted. The publication researched the population standard deviation of the battery life from the manufacturers. The population standard deviation for the Black Bear is assumed to be 0.71 hour, and the population standard deviation for the Grizzly is assumed to be 0.63 hour. The results of the battery life test are shown below. Assuming the conditions needed for the hypothesis test have been met, what is the z test statistic for this hypothesis test, rounded to two decimal places? Black Bear: x̄1 = 11.24 hours n1 = 54 Grizzly: x̄2 = 11.06 hours n2 = 51 Provide your answer below:
