6.A 2019 article in the American Journal of Public Health (AJPH) reports the results of a randomized study designed, as per the researchers, to "assess the effect of 2-way short message service (SMS) with a nurse on postpartum contraceptive use among individual women in Kenya".The reported results include the following prose:

"We randomized 260 women to 2-way SMS or control.At 6 months postpartum, 69.9% of the 130 women receiving SMS reported postpartum use of highly effective contraceptives (HEC), compared with 57.4% of the 130 women in the control arm".

The 95% confidence interval for the risk difference of HEC use at 6 months for the women receiving 2-way SMS messages compared to women who do not receive 2-way SMS messages (controls) is (0.01, 0.24). Based on this information, and your result from question 5, which of the following is the 95% confidence interval for estimated relative risk of HEC use at 6 months for the women receiving 2-way SMS messages compared to women who do not receive 2-way SMS messages (controls)?
