← The results of a survey on the belief that stem cell research has merit are shown in the table below. % X 1524 SEP 28 95% CI (0.7052, 0.7434) Here, X denotes the number who believed that stem cell research has merit. Complete parts a and b below. N 2104 a. Explain how to interpret "Sample p" and "95% CI" in this table. The "Sample p" is the proportion of all respondents in the sample who believe stem cell research has merit, 1524/2104 0.72. The "95% CI" is the 95% confidence interval and it means that we can be 95% confident that the interval 0.7052 to 0.7434 contains the population proportion.
