You measure 49 turtles' weights, and find they have a mean weight of 42 ounces. Assume the population standard deviation is 11.4 ounces. Based on this, construct a 95% confidence interval for the true population mean turtle weight. (Note you will use the z distribution for your critical value since the population standard deviation is given.) Write your answer in the form of point estimate±margin of errorpoint estimate±margin of error. Give your answers as decimals, to two places. ± Write your answer using inequality notation.  <μ<
