Solid fats are more likely to raise blood cholesterol levels than liquid fats. Suppose a nutritionist analyzed the percentage of saturated fat for a sample of 6 brands of stick margarine (solid fat) and for a sample of 6 brands of liquid margarine and obtained the following results: Stick : [26.2, 25.6, 25.5, 26.1, 26.5, 26.7] Liquid : [16.3, 16.4, 16.3, 16.7, 16.6, 17.7] We want to determine if there a significant difference in the average amount of saturated fat in solid and liquid fats. What is the test statistic? a) Oz= 32.335 b) Ot= 31.835 c) Oz= 31.835 d) Ot = 23.002 e) Ot= 32.335
