In the 1940s, the U. S. Department of Commerce reported a new way to test the tensile strength, in pounds per square inch, of concrete. Several samples of concrete specimens were used to estimate the mean tensile strength of 430 pounds per square inch with a margin of error of 10 pounds per square inch. After the study was published, another group proposes to run the same test on concrete
specimens but with samples including many more concrete specimens in each sample. Which of these statements is most likely to be true about the second study? (select one answer)

The margin of error for the second study will likely be around 10 pounds per square inch.

The estimated mean will be greater than 440 pounds per square inch.

The margin of error for the second study will likely be greater than 10 pounds per square inch.

The margin of error for the second study will likely be less than 10 pounds per square inch.
