a. Statistically significant at 0.01
b. Not statistically significant
Answer:
The test is significant
Step-by-step explanation:
When a p value is smaller than or less than alpha we say it is statistically significant.
We are testing the p value or likelihood of 0005 against a significant level of 0.01
P value = 0.005 < 0.01
0.005 is less than 0.01 which shows the test to be significant.
The decision rule would be to reject the null hypothesis and say the result is statistically significant.
