Plasma-glucose levels are used to determine the presence of diabetes. Eleven active people age 35- to 44-year-olds were sampled and their plasma-glucose levels were measured. Below is the R code with the R Output. The researcher believes that the plasma-glucose of these active people will be the same as the general population which has a mean of 4.86. Test at a significance level of 5% the researcher's belief. Assume normality of the population. (Round to the nearest hundredth 0.00) RCode: ```{r}Plasma_glucosesummary(Plasma_glucose)sd(Plasma_glucose)``` R Output 4.18, 4.82, 4.29, 4.28, 4.85, 4.73, 5.25, 5.41, 4.78, 5.43, 4.11 Min. 1st Qu.
