Colonial Funds claims to have a bond fund that has maintained a mean share price of $⁢18.00. They claim that the standard deviation of the share price is 0.14. To test this claim, the investor randomly selects 9 days during the last year. He finds an average share price of $⁢17.80 with a standard deviation of 0.1372. Can the investor conclude that the share price of the bond fund varies from Colonial Funds claims at α=0.05? Step 3 of 5 :   Determine the value of the test statistic. Round your answer to three decimal places.
