Suppose there are two different vaccines for Covid. Vaccine X and Vaccine Y. An interesting question is which vaccine has a higher 6-month antibody effectiveness quotient (6AEQ). To examine this we randomly select 78 recipients of vaccine X and 93 recipients on vaccine Y. The vaccine X recipients had a mean 6AEQ of x = 151. The vaccine Y recipients had a mean 6AEQ of y = 148. It is recognized that the true standard deviation of 6AEQ for vaccine X recipients is o, = 9.7 while it is recognized tha the true standard deviation of 6AEQ for vaccine Y recipients is o, = 10.5. The true (unknown) mean GAEQ for vaccine X recipients is y while the true (unknown) mean 6AEQ for vaccine Y recipients is y. 6AEQ measurements are known to be a normally distributed. In summary: Type Sample Size Sample Mean Standard Deviation Vaccine X78 Vaccine Y93 9.7 10.5 151 148 Calculate the standard deviation of X- ) If we wish to create an 96% confidence interval for ,- H, then what is the z critical value used?
