Answer:
What we know about the p-value for the test is that it will be less than 0.05
Step-by-step explanation:
The complete question is as follows;
Suppose that you had consumer group wanted to test to see if weight of participants in a weight loss program changed (up or down). They computed a 95% confidence interval of the result (-4.977, -2.177). Suppose that we had a significance test with the following hypothesis:
H0: population mean weight loss = 0
Ha: population mean weight loss does not equal 0
What do we know about the p-value for the test?
solution;
Given the information in the question, we are concerned with saying what we know about the p-value for the test
To answer this question, we shall be looking at it from the angle of the confidence interval
The confidence interval given is 95%.
Now what does this indicate?
It indicates that 95% confidence interval contains only values which are less than 0.
What does this mean for the p-value?
This means that the p-value will be less than 0.05
