Question 9 0 / 1 point The example provided in Appendix B asks this question: Two hypotheses were proposed: the predation hypothesis and the freeze hypothesis. Match each hypothesis with its null (Ho) and alternative components (HA) 1. South-facing slopes have less seed predation -2 Freeze HA Predation is equal on south- and north-facing slopes; another factor may affect saguaro distribution. 2. 4Predation HA 3 South-facing slopes are less likely to experience prolonged freezes, which kill _ Freeze Ho saguaros -3 Predation Ho South-facing slopes receive more direct sunlight than north-facing slopes, but the number of prolonged freezes does not affect the number of saguaros. 4 Question 10 0 1 point The prediction step of the scientific method is when you predict whether your hypothesis is "correct" or not True False

Explanation / Answer

Q9. When there is a significant difference between two conditions or data set then null hypothesis have to be rejected and alternative have to be accepted. But when there will be no significant difference between two conditions or data set null hypothesis is always accepted.

Q10.

No predictions are scientific. Predictions are just the assumption to accept the results before the experiment. It is often based upon experience. So the answer is false.

Freeze HA 3. South-facing slopes are less likely to experience prolonged freezes, which kills suguaros. Predation HA 1. South-facing slopes have less seed Predation. Freeze H0 4. South-facing slopes receive more direct sunlight than north facing slopes but the number of prolonged freezes does not affect the number saguaros. Predation H0 2. Predation is equal on south- and north-facing slopes, another factor may affect saguaro distribution.
