Dr. Kelly Roberts is dean of a medical school and must plan courses for incoming students. The college president is encouraging her to increase the emphasis on pediatrics, but Dr. Roberts argues that fewer than 10% of medical students prefer pediatrics. She refers to sample data indicating that 64 of 1068 randomly selected medical students chose pediatrics. Is there sufficient sample evidence to support her argument (at the 0.01 significance level)?
Test the given claim, and draw the appropriate graph. Use the traditional method or the P-value method of testing hypotheses (or your instructor may specify which method to use with assigned exercises). Assume that all samples have been randomly selected.
