. A manufacturer of chocolate chips would like to know whether its bag filling machine works correctly at the 426 gram setting. It is believed that the machine is underfilling the bags. A 99 bag sample had a mean of 417 grams with a variance of 400. A level of significance of 0.10.1 will be used. Assume the population distribution is approximately normal. Determine the decision rule for rejecting the null hypothesis. Round your answer to three decimal places. Reject H0 if t < blank
1. A manufacturer of chocolate chips would like to know whether its bag filling machine works correctly at the 426 gram setting. It is believed that the machine is underfilling the bags.

Reject H0 if t < blank ?
2.Using traditional methods, it takes 9.4 hours to receive a basic driving license. A new license training method using Computer Aided Instruction (CAI) has been proposed. A researcher used the technique with 24 students and observed that they had a mean of 9.6 hours with a standard deviation of 1.4. A level of significance of 0.1 will be used to determine if the technique performs differently than the traditional method. Assume the population distribution is approximately normal.
Find the value of the test statistic. Round your answer to three decimal places.
