A manufacturer of chocolate chips would like to know whether its bag filling machine works correctly at the 433433 gram setting. It is believed that the machine is underfilling the bags. A 4242 bag sample had a mean of 425425 grams. Assume the population variance is known to be 625625. A level of significance of 0.050.05 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.
