The Soft Rice Company makes a soft rice packet to be reheated in the microwave. When the machine which packages the rice is running properly, the average number of grams in the packet should be 500.To check the accuracy of the machine, six packets are filled by the machine and a technician carefully measures the weight in each package. In one such test, the following data were observed:

510

487

502

513

499

504

Based on these sample data, which of the following is true if the significance level is .05?

Group of answer choices

No conclusion can be reached about the status of the machine based on a sample size of only six cups.

The null hypothesis cannot be rejected since the test statistic is approximately t = 0.60, which is not in the rejection region.

The null hypothesis can be rejected since the sample mean is greater than 14.

The null can be rejected because the majority of the sample values exceed 14.
