The mean weight for college students is 175 pounds. A sample of 30 students at a college is taken, and the mean of the sample is 180 pounds with standard deviation 20 pounds. A company wants to see if the weights of the students at the college are statistically different from the national average at the 95% confidence level. Find the p-value in the table for the table value of t closest to the calculated value of the test statistic (round to 2 decimal places).
