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:[26.4,25.5,25.8,26.1,25.6,26.3] Liquid:[16.9,16.9,17.2,17.3,16.3,17.1] 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) t = 42.744 b) z = 42.244 c) t = 42.244 d) z = 42.744 e) t = 25.816
