A random sample of 12 tests for two different drugs revealed the following times (in minutes) until the effects of the drug were neutralized. Drug A Drug B a. Calculate the mean and standard deviation for each of the two drugs. b. Based on the sample means calculated in part a, which drug appears to be effective longer? c. Based on the sample standard deviations calculated in part a, which drug appears to have the greater variability in effect time? d. Calculate the sample coefficient of variation for the two drugs. Based on the coefficient of variation, which drug has the greater variability in its time until the effect is 210 282 299 278 252 274 286 266 283 269 283 260 O 259 218 243 230 240 223 244 249 242 237 250 214 neutralized? a. What is the mean of drug A? (Round to two decimal places as needed.)
