In one set of Mendel’s pea experiments, he crossed a round-green pea with a wrinkled-yellow pea (Mendel, 1866). The result of this cross gave him a round-yellow pea. He then crossed two of these round-yellow peas together and got the results shown in the following table. He conjectured that this type of crossing should result in a 9:3:3:1 ratio with the pea types in the order shown in the table. Do we have convincing evidence that the proportions of pea types are not distributed in this 9:3:3:1 ratio? Test as follows: 

a. State the hypotheses in words or in symbols. 

b. Calculate the test statistic, and p-value. 

c. State your conclusion in the context of the research question.
