HUCDLIUII 1.! \\J. PUIIIL, in 2021, for the first time, WHO approved a malaria vaccine for children in endemic malaria areas. Suppose WHO sets a target to have 80% of children in endemic malaria areas vaccinated against malaria within 12 months after the large-scale vaccination begins. You take a sample of 200 children and identify which of the children in your sample are vaccinated - so the variable vaccine is set to 1 for those children who are vaccinated and set to 0 for those children who are not vaccinated. The following is the output of a Stata prtest procedure run on your sample. Which of the following statements best describes your conclusions from the results of this prtest? . prtest vaccine "0.80 One-sample test of proportion Number of obs - 20. Variable Mean std. err.

( b) You have not yet met your target because the P value is 0.0518, so your result is not statistically significant. O c) The data do not show that you have failed to meet your target because the 95% confidence interval contains 80%. O d) You have met your target because the 95% confidence interval contains 80%
