A group 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 43 cables and apply weights to each of them until they break. The 43 cables have a mean breaking weight of 775.3 lb. The standard deviation of the breaking weight for the sample is 15.3 lb. Find the 90% confidence interval to estimate the mean breaking weight for this type cable. 1. The t value is 2. The standard error has a value of - 3. The margin of error has a value of 4. Find the 90% confidence interval to estimate the mean breaking weight for this type cable -
