Show transcribed image text 2) Experience of potato farmers in a certain region of the country is that the expected potato yield is 40 t/ha (tonnes per hectare) with standard deviation 1.5 t/ha. A particular farm is studied and each of 5 different hectares on the farm are observed to have yields of 40.71,39.44,40.36, 39.98, and 40.58. Assume that the standard deviation given above holds at this farm. a) Does the evidence suggest that the yield is not 40 t/ha at this farm? Test at a significance level of 5%. b) What is the p-value for this test?
