Question
A scientist wants to determine if a new fertilizer increases the average yield of crops. What type of hypothesis test should the scientist perform?Group of answer choicesRight-tailed testLeft-tailed testTwo-tailed testNo answer text provided.
Solution
The scientist should perform a right-tailed test. This type of test is used when the alternative hypothesis suggests that the mean of the sample is greater than the mean of the population. In this case, the scientist is looking to see if the new fertilizer increases (i.e., is greater than) the average yield of crops.
