An important measure of the risk associated with a stock is the standard deviation,or variance,of the stocks price movements. A financial analyst wants to test the one tailed hypothesis that stock A has a greater risk(larger variance of price) than stock B.A random sample of 25 daily prices of stock A gives s^2A=6.52 and a random sample of 22 daily prices of stock B gives a sample variance of s^2B=3.47. Carry out the test at alpha=0.01.
