Scientists are working on a synthetic vaccine (antigen) for a particular parasite. The success of the vaccine hinges on the characteristics of DNA in peptide (protein) produced by the ant one study, scientists tested alleles of antigen-produced protein for level of peptide. For a sample of 4 alleles, the mean peptide score was 1.39 and the standard deviation was 0.16. a. Use this information to construct a 90% confidence interval for the true mean peptide score in alleles of the antigen-produced protein. b. Interpret the interval for the scientists. c. What is meant by the phrase "90% confidence?"
