Chicken Feed A farmer fed different diets to two groups of 1

Chicken Feed: A farmer fed different diets to two groups of 100 chicks each. Assume that all factors other than the diets have been kept equivalent for the two groups. For those chicks fed diet A, the average weight gain in two weeks, for those chicks that survived, was 25 ounces with a standard deviation of 5 ounces, however, 13 chicks died during the period. For those fed diet B, the average weight gain in two weeks, again for those chicks which survived, was only 15 ounces with a standard deviation of 4 ounces, but only 7 chicks died. Using this data, answer the following questions

Q1 The death data for the chicks can be summarised in a 2x2 table as:

Conduct a chi-squared test of independence/homogeneity for this table and relate your result to the result from Question 1 above.
