A researcher is investigating whether a new fertilizer affects the yield of tomato plants. As part of an experiment, 20 plants will be randomly assigned the new fertilizer and 20 will be assigned the current fertilizer. The mean number of tomatoes produced per plant will be recorded for each fertilizer, and the difference in the sample means will be calculated. Which of the following is the appropriate inference procedure for analyzing the results of the experiment?a)A matched-pairs t-interval for a mean differenceb)A two-sample t-interval for a difference between sample meansc)A two-sample t-interval for a difference between population meansd)A one-sample t-interval for a sample meane)A one-sample t-interval for a population mean

The correct answer is (c) option.

The following information should be considered:

The experiment is conducted for measuring whether a new fertilizer impacts the yield of tomato plants or not After this, the mean number of tomatoes produced per plant will be recorded for each fertilizer, and the difference in the sample means will be determined. The researchers main focus is to measured whether the new fertilizer is effective or not. Thus, the parameter under study is the difference between two population means. For make inferences related to the experiment the researcher can construct a two-sample t-interval for a difference between population means. The confidence interval has a specific probability of involving the true parameter value.

Correct option is (c).

Step-by-step explanation:

The experiment is conducted to determine whether a new fertilizer affects the yield of tomato plants.

The procedure involves randomly assigning the new fertilizer to 20 plants and the other 20 will be assigned the current fertilizer.

Then the mean number of tomatoes produced per plant will be recorded for each fertilizer, and the difference in the sample means will be calculated.

The collected sample data will then be used to make conclusion about the population.

The researchers main aim is to determine whether the new fertilizer is effective or not, i.e. if on using the new fertilizer the yield of tomatoes increases or not.

So, the parameter under study id the difference between tow population means.

To make inferences about the experiment the researcher can construct a two-sample t-interval for a difference between population means. The confidence interval has a certain specific probability of including the true parameter value.

Thus, the correct option is (c).
