A study was conducted to determine whether the mean braking distance of four-cylinder cars is greater than the mean braking distance of six-cylinder cars. A random sample of 20 four- cylinder cars and a random sample of 20 six-cylinder cars were obtained, and the braking distances were measured.

(a) What would be the appropriate hypothesis test for this analysis? (i) t-test for two independent samples

(ii) t-test for dependent samples

(iii) z-test for population mean

(iv) correlation

(b) Explain the rationale for your selection in (a). Specifically, why would this be the appropriate statistical approach?
