Advanced Mathematical Decision Making

A random sample of 12 female students yielded a mean of 0.45 and standard deviation of 1.5. 99% CI to estimate the true mean weight change is (-0.8949 , 1.7949). Would you believe me if I claimed the average weight change was 0? How would you answer this using the hypothesis testing? Specify the hypothesis. Show test statistics= 1.04 ................
