A company operates three machines during three shifts each day. From production records, the data in the table below were collected.

At the .05 level of significance test to determine if the number of breakdowns is independent of the shift.

Question 9 options:

Yes, you can reject the claim that the number of breakdowns is independent of the shift because the p-value = 0.0423

Yes, you can reject the claim that the number of breakdowns is independent of the shift because the p-value = 0.9577

No, you cannot reject the claim that the number of breakdowns is independent of the shift because the p-value = 0.0423

No, you cannot reject the claim that the number of breakdowns is independent of the shift because the p-value = 0.9577

Question 10(1 point)

The data presented in the table below resulted from an experiment in which seeds of 4 different types were planted and the number of seeds that germinated within 4 weeks after planting was recorded for each seed type.

At the .05 level of significance, is the proportion of seeds that germinate dependent on the seed type?
