A consumer group wants to estimate the mean amount of fat, , in a certain brand of cookies. A random sample of n = 5 cookies shows the following fat content (in grams) in each: 5.7 5.0 5.3 5.6 5.4 1. What is, the mean amount of fat (in grams) for this sample? 2. Which of the following is s, the standard deviation of this sample? (You might receive credit for showing your work in calculating the value of s a) s= 0.060 b) s= 0.075 c) = 0.245 d) 8 = 0.274 3. If the consumer group wants to report their findings as a 90% confidence interval for u, what value of t (from the t-table) should they use in that formula? 4. Fill in the blanks below for the 90% confidence interval for u. (Make your answers accurate to two decimal places.) <p<.
