A peony plant with red petals was crossed with another plant having streaky petals. A geneticist states that 75% of the offspring from this cross will have red flowers. To test this claim, 100 seeds from this cross were collected and germinated, and 56 plants had red petals. Use the chi-square goodness-of-fit test to determine whether the sample data confirm the geneticist's prediction. (Use a = 0.01. Use P1 for the probability of having red flowers and p, for the probability of having streaky petals.) State the null and alternative hypotheses. Ho:P1 = 0.75; P2 = 0.25 %3D : At least one p; На is different from the specified value. Ho: P1 = 0.56; P2 H: At least one p, is different from the specified value. = 0.44 %D H: At least one p, is different from the specified value.
