Casein is a common weight gain supplement for humans, and so it might also increase chicken weight. An experiment was conducted, where 14 chickens (group 1) were given ordinary soybean-based food and 12 chickens (group 2) were given food supplemented with casein. Does casein lead to significantly higher average chicken weight?Use & = 0.05 and assume that chicken weight is roughly normally distributed. 2A. What are the null and alternative hypotheses? For the 14 soybean-fed chickens, sample mean weight was 246.43 with sample standard deviation 54.13. For the 12 casein-fed chickens, sample mean weight was 323.58 with sample standard deviation 64.43. 2B. Compute the test statistic for this data. 2C. Compute the -value. For the Welch two-sample t test, there are 21 degrees of freedom. 2D. Make a decision and briefly explain your decision
