Determine if the following statement is true or false.​ Why? The expected frequencies in a​ chi-square test for independence are

found using the formula below.
Expected frequency = (row total)(column total) / table total
Choose the correct answer below.
1. False. This formula gives the expected proportion. The (table total) factor in the denominator on the right should be squared.
2. True. It is a simplification of multiplying the proportion of a row variable by the proportion of the column variable to find the proportion for a cell, then multiplying by the table total.
3. True. The area to the right of this value in the corresponding chi-square distribution gives the P-value for the test.
4. False. The expected frequencies for a chi-square test are given by Oi - Ei/ Ei where i represents cell number.

600+15y=750.<br> solve for y<br> can I as well have the way you solved for y?
Pie
1.)subtract 600 from 750 in order to simplify
2.)divide by 15 on both sides to get y alone. Doing this cancels the 15 on the y and makes the right side equal 10
3.)y=10
