A researcher speculates that because of differences in diet, Japanese children have a lower mean blood cholesterol level than U.S. children do. Suppose that the mean level for U.S. child known to be 165. Let u represent the true mean blood cholesterol level for Japanese children. What hypotheses should the researcher test? O Ho: μ = 165 versus H₂: μ > 165 O Ho: μ = 165 versus H₂: μ< 165 O Ho: μ = 165 versus H₂: μ< 175 O Ho: μ = 175 versus H₂: μ> 165 O Ho: μ = 165 versus H₂: > 155
