Your Ear Class Total Observed Class Total Expected Purple Kernels $18 493.38 Yellow Kernels 165.5 163.67 x² = 7. Test the validity of the class's data using the chi-square test. The chi square is a simple mathematical calculation which can be used to determine how well the observed experimental data (your actual results) fits the theoretical prediction (the expected results). The formula for the chi-square is: (0₁-e₁)² (0₂- €₂)² e1 e2 + Total Kernels 683.5 657.05 X² = the symbol for the term, chi-square o = observed count (number) (o1 = the number of purple, 02 = the number of yellow) e = the expected number according to the predicted ratio. All en must be calculated for your sample To calculate the expected numbers for your 3:1 monohybrid cross: a. You expect % of your sample (total # of kernels) to be purple e₁ = your sample (total #) multiplied by 4 (round to the nearest whole number and record in the table) b. You expect 1 of your sample (total # of kernels) to be yellow e₂ = your sample (total #) multiplied by 4 (round to the nearest whole number and record in the table) 8. Now use the formula to calculate the chi-square value X² and show your work.

For most cases, a p value of 0.05 is used to determine whether results fit expected values. Is this a magic number, or could p values be set more stringently, say 0.01, or more lax, say 0.10? What effect would these values have on the reliability of the chi-square test?
Are these all correct? Last two questions are 8. What is the critical value? Round to two decimal places. 9. What is your conclusion from the chi-square test? option 1: Fail to reject H option 2: Reject Ho
