Nikulasa can buy certain type of string from one of two suppliers. The suppliers' products appear to be compatible in all respects except price and possibly breaking strength. Nikulasa will buy from supplier 1 (whose price is lower) unless there is reason to believe that supplier 1's product has lower mean breaking strength than supplier 2. Random sample are drawn from the two suppliers' stocks with the following results. Assume that the breaking strengths are normally distributed, variances are equal, and significance level at 0.01. (Source: Adapted) Results Supplier 1 sample size =10 sample mean= 94 sample std. deviation = 3.74 Supplier 2 sample size = 12 sample mean = 98 sample std. deviation = 3
