In recent years, a substantial amount of research has focused on a possible relationship between chemical contamination of various sorts and mental impairment in children. An article reported data on hair-lead concentration for a sample of mentally impaired children for which the cause of impairment was unknown. Sample statistics were n = 42 X Bar = 15.83 ppm s = 7.56 ppm The paper states that 14.85 ppm is considered the acceptable upper limit of hair-lead concentration. Let μμ= the average hair-lead concentration for all mentally impaired children with the cause of impairment unknown. H0: μμ = 14.85 versus H1: μμ > 14.85 at 0.01 significance level Does the given sample data support the research hypothesis that true average hair concentration for all such mentally impaired children exceeds the acceptable upper limit? Assume normality. Reject Null Hypothesis Fail to Reject Null Hypothesis

If the spindle is either too small or too large, the motor will not work properly. The manufacturer measures the diameter in a sample of 13 spindles to determine whether the mean diameter has moved away from the required measurement.
