Question

im confused about using the Chi square value to answer these questions

Complete the Chi Squared analysis below by filling in the empty white cells. Do not round numbers up until the very end (the final chi squared value) which you can round to one decimal place. It's best to do this in Excel or another spreadsheet program.

(2 pts) State the statistical null hypothesis. 8. (2 pts) Do your data disprove the null hypothesis? h. (1 pt) Do your data disprove the experimental hypothesis which is the two genes studied are on different chromosomes and therefore assort independently, and the two alleles for each gene show a relationship of complete dominance"?
