In a 4-week study about the effectiveness of using magnetic insoles to treat plantar heel pain, 50 subjects wore magnetic insoles and 45 subjects wore nonmagnetic insoles. The results are shown at the right. At a = 0.07, can you support the claim that there is a difference in the proportion of subjects who feel better between the two groups? Assume the random samples are independent. Complete parts (a) through (e). Do you Feel Better? Magnetic Insoles | Yes 17 | No 33 Nonmagnetic Insoles | Yes 18 No 27
