An investigator wishes to estimate the proportion of Type II diabetic patients who take insulin to manage their diabetes. A random sample of 270 Type II diabetics was sampled and X of those reported taking insulin to manage their diabetes. An analysis of this information was done in R and the output for the analysis is given below: 1-sample proportions test with continuity correction . data: X out of 270, null probability 0.5 X-squared = 4.537, df = 1, p-value = 0.03317 alternative hypothesis: true p is not equal to 0.5 95 percent confidence interval: 0. 505 0. 626 What is the sample proportion of those who reported taking insulin to manage their diabetes? O 0.65 O 0.57 O 0.60 O 0.51
