1)Null Hypothesis H0: The probabilities given by genetic theory are correct.
2) Expected count for red seeds =
3) Under null hypothesis , the test statistic is
4) Degrees of Freedom = n-1 = 3-1 = 2
5) The P-Value is 0.75352
P value >0.1
Conclusion : There is no evidence against the null hypothesis that the probabilities given given by genetic theory hold.

According to genetic theory, the blossom color in the second generation of a certain cross of sweet peas should be red or white in a 3:1 ratio. That is, each plant has probability 3/4 of having red blossoms, and the blossom colors of separate plants are independent. a. What is the probability that exactly three out of four of these plants have red blossoms? b. What is the mean number of red-blossomed plants when 60 plants of this type are...
According to genetic theory, the blossom color in the second generation of a certain cross of sweet peas should be red or white in a 3:1 ratio. That is, each plant has probability 3/4 of having red blossoms, and the blossom colors of separate plants are independent. (a) What is the probability that exactly three out of nine of these plants have red blossoms? (Round your answer to four decimal places.) (b) What is the mean number of red-blossomed plants...
Samples of three different species of amphibian (frog, toad and salamander) were collected and dissected and the number of parasites found within each was counted and recorded. The researchers are interested in determining whether the distribution of parasites across species is different. The number of parasites within each sample was counted and recorded. Toads Frogs Salamanders 15 8 6 15 3 3 5 16 4 2 2 5 8 4 4 6 2 8 18 0 4 6 2 7...
2. According to genetic theory, there are three blood types MM, NM and NN which should occur in a very large population with probabilities, O, (1-9)3 and 30(1-0), where is the (unknown) gene frequency, 0 s 0S1. (Note: This distribution is for exercise purposes only and may not be true in real life.) (a) Suppose that in a random sample of size n = 10 from the population, there are f, f, and fs of types MM, NM and NN...

The diet of peregrine falcons consists of songbirds, shorebirds, and waterfowl. Typically, songbirds are smaller than shorebirds, which are smaller than waterfowl. The female peregrine is considerably larger than the male, with a length of 46-54 cm, compared to 38-46 cm for the male. Data were collected on the prey of a number of peregrines of each sex for the purpose of determining whether or not the larger females more regularly capture the larger prey, with the results below. Prey...

In Study Design 2, Super Sneaker Company drew at random two groups of 14 high school students from the Halifax school district database. After obtaining their shoe sizes, the company manufactured 14 pairs of shoes for group 1, each pair with both soles constructed from material A, and 14 pairs of shoes for group 2, each pair with both soles constructed from material B. After 3 months, the amount of sole wear in each shoe was recorded in standardized units,...
I have tried 4 which was incorrect For a comparison of two study guides for a mathematics course, 12 student volunteers were found. They were randomly assigned, 6 to study guide A, and 6 to study guide B. Following a two-day period of independent study, the students were examined on the material. The students received the following scores (out of 100): Study Guide A: 98 88 89 79 96 89 Study Guide B: 76 63 80 69 82 65 Use...
Super Sneaker Company is evaluating two different materials, A and B, to be used to construct the soles of their new active shoe targeted to city high school students in Canada. While material B costs less than material A, the company suspects that mean wear for material B is greater than mean wear for material A. Two study designs were initially developed to test this suspicion. In both designs, Halifax was chosen as a representative city of the targeted market....
