Question

CONCLUSIONS: In a test population of 1000 people, 200 display albinism. You hypothesize that this trait follows Mendelian genetics with a 3:1 ratio of no albinism to albinism. Use the Χ2 test to determine whether the data support the hypothesis or not.

a) The data support the hypothesis.
b) The data do not support the hypothesis.
c) The chi-square value is not provided.
d) The expected ratio is 1:3.

Answer 1

To determine if the data supports the hypothesis of Mendelian genetics, use the chi-squared test to compare observed and expected results.

Step-by-step explanation:

The student can use the chi-squared test to determine whether the data supports the hypothesis of Mendelian genetics with a 3:1 ratio of no albinism to albinism. The chi-squared test is a statistical test that evaluates the difference between observed and expected results. To conduct the test, the student needs to calculate the chi-square value using the formula: χ2 = Σ((Observed - Expected)^2 / Expected). Then, compare the calculated chi-square value with the critical value from the chi-square table with the given degrees of freedom. If the calculated chi-square value is less than the critical value, the data supports the hypothesis (option a). If it is greater than the critical value, the data does not support the hypothesis (option b).
