A corporation sets its annual budget for a new plant on the assumption that the average weekly cost for repairs is to be μ = 1,200. To see whether this claim is realistic, 10 weekly repair cost figures are obtained from similar plants. The sample is assumed to be random and yield = 1,290 and s = 110. The computed t is 2.587.
