The total cholesterol level of each participant (in [tex]$mg / dL$[/tex]) is recorded once at the start of the study and then again after three months of taking the drug. The results are given in the following table. Construct a [tex]$90 \%$[/tex] confidence interval for the true mean difference between the cholesterol levels for people who take the new drug. Let Population 1 be the initial cholesterol level and Population 2 be the cholesterol level after three months. Round the endpoints of the interval to one decimal place, if necessary. | Total Cholesterol Levels (in mg/dL) | |---|---| | Initial Level | Level after Three Months | | 185 | 202 | | 193 | 206 | | 191 | 217 | | 182 | 220 | | 190 | 183 | | 198 | 214 | | 190 | 217 | | 203 | 218 | | 189 | 183 | | 226 | 210 | | 185 | 186 | | 204 | 209 | | 183 | 208 | | 227 | 211 | | 197 | 208 |
