# Agroup of engineers developed a new design for a steel cable. they need to estimate the amount of weight the cable can hold. the weight limit will be reported on cable packaging. the engineers take a random sample of 41 cables and apply weights to each of them until they break. the 41 cables have a mean breaking weight of 772.3 lb. the standard deviation of the breaking weight for the sample is 15.3 lb. find the 95% confidence interval to estimate the mean breaking weight for this type cable. ( 11.74 , 12.86 ) your answer should be to 2 decimal places.
