Confidence Intervals for Population Proportion: Videos & Practice Problems

Researchers compared two diets for weight loss. In diet alpha ($n=180$), $60$ participants lost at least $10$ $\text{kg}$ in $6$ months. In diet beta ($n=170$), $38$ participants achieved the same result. Estimate the difference in the proportion of participants losing at least $10$ $\text{kg}$ between diet alpha and diet beta with $95\%$ confidence.
