Antigens for a parasitic roundworm in birds. Refer to the Gene Therapy and Molecular Biology (June 2009) study of DNA in peptide (protein) produced by antigens for a parasitic roundworm in birds, Exercise 7.50 (p. 364).

Recall that scientists tested each in a sample of 4 alleles of antigen-produced protein for level of peptide. The results were: x = 1.43 and s = .13. Use this information to construct a 90% confidence interval for the true variation in peptide scores for alleles of the antigen-produced protein. LO6 Interpret the interval for the scientists.
