In a 4-week study about the effectiveness of using magnetic
insoles to treat plantar heel pain, 54 randomly chosen subjects
wore magnetic insoles and 41 randomly chosen subjects wore
nonmagnetic soles. When asked if they felt better, 17 of the
magnetic sole wearers said yes, and 18 of the nonmagnetic sole
wearers said yes also. Construct and interpret a 95% confidence
interval for the difference in proportion of subjects who said they
feel better after wearing magnetic or nonmagnetic insoles.
Fill in the appropriate blanks to complete the confidence interval.
I am 95% confident that the interval from Select]
& to
гу
[Select)
captures the true difference of the
proportions. There is
convincing evidence of a
significant difference in the proportions.
