Although many people think they can put a meal on the table in a short period of time, a recent article reported that they end up spending about 40 minutes doing so. Suppose another study is conducted to test the validity of this statement. A sample of 25 people is selected, and the length of time to prepare and cook dinner is recorded with mean=45.628 minutes, standard deviation=6.9587 minutes. Is there evidence that the population mean time to prepare and cook dinner is greater than 40 minutes? Use a level of significance of 0.05. Determine the p-value and interpret its meaning.
