###### In a 4-week study about the effectiveness of using magnetic insoles to treat plantar heel pain,...

In a 4-week study about the effectiveness of using magnetic insoles to treat plantar heel pain, 52 subjects wore magnetic insoles and 41 subjects wore nonmagnetic insoles. The results are shown at the right. At a =0.06, 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 14 No 38 Nonmagnetic Insoles Yes 16 No 25 (a) Identify the claim and state Ho and H, The claim is "the proportion of subjects who feel better with magnetic Insoles is different than those who feel better with nonmagnetic insoles." Let P, represent the population proportion for the magnetic insoles and P2 represent the population proportions for the nonmagnetic insoles. State Ho and H. Click to select your answer(s).
