The mean body mass index (BMI) in patients free of diabetes was reported as 28. An investigator conducting the study hypothesizes that the BMI in patients free of diabetes is different than 28. Based on the data found in a simple random sample of n=12, the mean and standard deviation of BMI were found to be 32 and 6, respectively. Based on this is there evidence that the BMI is significantly different than 28? Use a 5% level of significance? Note: Round your answers to three decimals. None of these choices are correct. T-stat 2.310, T-critical value = 2.201. Since 2.310> 2.201 Reject Ho. T-stat 2.201, T-critical Value = 2.310. Do = not reject HO since 2.210 < 2.310. O T-stat 2.310, T-critical value = = 2.179. Reject HO since 2.310 > 2.179.
