An experiment in chicken breeding results in оffspring hаving very curly, slightly curly, оr nоrmаl feаthers. If this is the results of a single gene system, then the proportions of offspring in the three phenotypes should be 0.25, 0.50, and 0.25 respectively. In one such experiment, 100 chickens were born in which 31 had very curly feathers, 57 had slightly curly feathers and 12 had normal feathers. Carry out a test to determine whether the genetic model seems to hold in this setting. Use a 5% level of significance. Show all work for full credit. a. State the null and alternate hypotheses. b. Compute the test statistic. c. Find the critical value and/or the p value. d. Make a decision and justify it using the critical value and/or the p-value. e. Record an appropriate conclusion in context of this problem.
