Math 43 HW 9 Sections 9.1-9.3 1) Studies have shown that only 28% of Americans that live in states without handsfree laws use a hand-free device while talking on a cell phone. A researcher is interested in doing a test to see if this percentage is higher in states that have laws requiring the use of hands-free devices while driving. Assume σ ≈ 0. 0199 a) Determine H0 and H1. b) Is this a left-tailed, right-tailed or two-tailed test? c) If the sample proportion was 0.29, would this be considered strong evidence to reject H0? Explain.
