A manufacturer of chocolate chips would like to know whether its bag filling machine works correctly at the 422 gram setting. It is believed that the machine is underfilling the bags. A 22 bag sample had a mean of 413 grams with a standard deviation of 21. Assume the population is normally distributed. A level of significance of 0.02 will be used. Find the P-value of the test statistic. You may write the P-value as a range using interval notation, or as a decimal value rounded to four decimal places.
