Extracted text: Scientists are working on a synthetic vaccine (antigen) for the parasitic roundworm. The success of the vaccine hinges on the characteristics of DNA in the peptide (protein) produced by the antigen. In the journal, Gene Therapy and Molecular Biology (June 2009), scientists tested alleles of antigen-produced protein for the level of the peptide. For a sample of 24 alleles, the mean peptide score was 1.83 and the standard deviation was .15. Use this information to construct a 95% confidence interval for the true mean peptide score in alleles of the antigen-produced protein.
