The Consumer Fraud Council claims that a well known brand does not put the required weight of peanut better in its 10-ounce jar. For evidence, a sample of 400 jars is selected randomly, weighed, and found to average 9.9. ounces. The p-value, .07, is associated with the hypothesis that the population mean (u) is usually 10 ounces and the production process is not generating "light" bottles.

Has the council proved the point?
Evaluate the evidence. Is the evidence statistically significant at the .10 level? At the .05 level?
Should the Consumer Fraud Council recommend a boycott? Why or why not?
