We wish to test if a new feed increases the mean weight gain compared to an old feed. At the conclusion of the experiment it was found that the new feed gave a 8 kg bigger gain than the old feed. A two-sample t-test with the proper one-sided alternative was done and the resulting p-value was 0.009. This means:

Question
We wish to test if a new feed increases the mean weight gain compared to an old feed. At the conclusion of the
experiment it was found that the new feed gave a 8 kg bigger gain than the old feed. A two-sample t-test with the
proper one-sided alternative was done and the resulting p-value was 0.009. This means:
O There is only an 0.9% chance of getting a 8 kg increase.
There was only an 0.9% chance of observing an increase greater than 8 kg (assuming the null hypothesis
was false).
O There is an 0.9% chance the null hypothesis is true.
O There is an 0.9% chance the alternate hypothesis is true.
There was only a 0.9% chance of observing an increase greater than 8 kg (assuming the null hypothesis
was true).
