Document Summary
We look for the shaded area to the right 1. 27 (because of the direction of the alternative hypothesis). From table 2 we can find the p-value. Interpretation: if the null hypothesis were true, and the sonnet"s were written by this poet. there is a 10% chance of obtaining the sample mean that we obtained. A cheese manufacturer buys milk from suppliers, there is a suspicion that one of the suppliers is watering down the milk to increase profits. What do we know about the milk? natural whole milk has a freezing point known to. = -0. 545 c and = 0. 008. if we add water the freezing point would vary normally with then increase to 0 c. The shipments from the suspect supplier are sampled on 5 occasions and the freezing point of each sample is determined to be -0. 538 c. conduct this test at the 5% level of significance.
