A dairy farm uses the somatic cell count (SCC) report on the milk it provides to a processor as one way to monitor the health of its herd. The mean SCC from five samples of raw milk was 250,000 cells per milliliter with standard deviation 37,50o cell/ml. Test whether these data provide sufficient evidence, at the 10% level of significance, to conclude that the mean SCC of all milk produced at the dairy exceeds that in the previous report, 210,250 cell/ml. Assume a pormal distribution of SCC

Question
A dairy farm uses the somatic cell count (SCC) report on the milk it provides to a processor as
one way to monitor the health of its herd. The mean SCC from five samples of raw milk was
250,000 cells per milliliter with standard deviation 37,50o cell/ml. Test whether these data
provide sufficient evidence, at the 10% level of significance, to conclude that the mean SCC of
all milk produced at the dairy exceeds that in the previous report, 210,250 cell/ml. Assume a
normal distribution of SC.
