8.4.1B. In a​ 4-week study about the effectiveness of using magnetic insoles to treat plantar heel​ pain, 51 subjects wore magnetic insoles and 43 subjects wore nonmagnetic insoles. The results are shown at the right. At α=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?
