Question

You measure 41 dogs' weights, and find they have a mean weight of 36 ounces. Assume the population standard deviation is 13.8 ounces. Based on this, construct a 95% confidence interval for the true population mean dog weight. Use z for the critical value. Give your answers as decimals, to two places ± ounces
