A researcher conducted a Chi-square test to determine whether the progeny of oyster mushroom follows the ratio of 3 grey: 1 white. From his calculation, he found his calculated Chi-square is smaller than the critical Chi-square value from the table. Which one is the CORRECT conclusion?   a. Null hypothesis cannot be rejected. The progeny ratio is different than the expected ratio.   b. Null hypothesis is rejected. The progeny ratio follows the expected ratio. c. The ratio of the progeny from his experiment does not follow the ratio 3:1.   d. The ratio of the progeny from his experiment is consistent with the ratio 3:1.
