Suppose that the null and alternative hypotheses for a study on the average weight for an animal species are given below: H0∣μ=32.1mg Ha∣μ≠32.1mg Assume that you construct a confidence interval from a sample that is given by: (C.I.)μ95%=(38.5,48.2)mg Define δto be the distance from the null-hypothesis claim to the closest boundary of the obtained confidence interval. This is one metric that can be used to determine the "strength" of the hypothesis test conclusion. What is the value of δfor this...
