A maker of a certain brand of low-fat cereal bars claims that the average saturated fat content is 0.4 gram. In a random sample of 8 cereal bars of this brand, the saturated fat content was as shown below. 0.6 0.3 0.6 0.6 0.2 0.3 0.6 Would you agree with the claim? Assume a normal distribution. 0.5 Click here to view page 1 of the table of critical values of the t-distribution. Click here to view page 2 of the table of critical values of the t-distribution. The computed t-value is t = ☐, so P(T>t) is This evidence to disagree (Round to two decimal places as needed.) greater than 0.40. between 0.30 and 0.40. between 0.10 and 0.15. between 0.20 and 0.30. less than 0.01. between 0.15 and 0.20.
