K In a 4-week study about the effectiveness of using magnetic insoles to treat plantar heel pain, 52 subjects wore magnetic insoles and 39 subjects wore nonmagnetic insoles. The results are shown at the right. At a=0.09, 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 21 No 31 Nonmagnetic Insoles Yes 20 No 19 Let p represent the population proportion for the magnetic insoles and p2 represent the population proportions for the nonmagnetic insoles.
