ANSWER:Step 1 of 2
Adult-onset diabetes is known to be highly genetically determined. A study compared frequencies of a particular allele in a sample of such diabetics and a sample of non-diabetics. The data are shown in the following table:
Ho: The null hypothesis states that the ALLELE frequencies in diabetics and non-diabetics are the same.
Test statistics:
The test statistics under Ho is,
Where,
I = Number of rows.
J = Number of columns.
The table for the observed frequencies can be drawn as follows:
Expected frequencies can be calculated as:
