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:[26.4,25.8,25.8,25.5,26.7,25.7] Liquid:[17.5,16.3,16.7,17.3,17.3,16.8]   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) z = 33.883 b) t = 22.982 c) t = 33.383 d) t = 33.883 e) z = 33.383
