The owner a dairy farm claims that each of his milking cows can produce an average of 120 liters of milk per week. A representative from a certain dairy company visited the farm and randomly selected a sample of 26 cows and recorded that amount of milk produced by each cow for one week. The observations are presented below (in liters): 119 125 120 122 130 118 121 123 125 117 115 121 122 117 120 121 124 127 115 126 119 124 115 116 120 124 At 0.05 level of significance, do the sample data contradict the owner's claim? (Assume that the distribution of milk is normally distributed.) Perform all 7 steps hypothesis testing for testing one population mean
