An investor wants to invest his money in a fund which has maintained a steady value. A fund manager claims that one of his bond funds has maintained an average price of $13.00 with a variance of 0.2. In order to find out if the fund manager's claim is true, the investor samples the prices from 22 random days and finds a standard deviation of 0.3167 in the price. Can the investor conclude that the variance of the share price of the bond fund is different than claimed at α=0.01? Assume the population is normally distributed. Step 1 of 5 : State the null and alternative hypotheses. Round to four decimal places when necessary.
