Reference no: EM13624866

A trucking company wants to estimate the weight load capacity of a particular brand of their flatbed trucks. In measuring 13 of their trucks the average load capacity was 2646 pounds, with a sample standard deviation of 845 pounds. A t-interval was computed to be:

( 2017.7 pounds, 3274.3 pounds)

What confidence level does this interval represent?

80%

90%
