Repeat Exercise 19 Old Faithful using the standard deviation instead of the mean. Compare the confidence interval

Question:

Repeat Exercise 19 "Old Faithful" using the standard deviation instead of the mean. Compare the confidence interval to the one that would be found using the methods of Section 7-3. If the two confidence intervals are very different, which one is better? Why?
Repeat exercise 19
Use these Old Faithful eruption duration times (seconds):
125 203 205 221 225 229 233 233 235 236 236 237 238 238 239 240 240 240 240 241
241 242 242 242 243 243 244 245 245 245 245 246 246 248 248 248 249 249 250 251
252 253 253 255 255 256 257 258 262 264
a. Use the bootstrap method with 1000 bootstrap samples to find a 95% confidence interval estimate of μ.
b. Find the 95% confidence interval estimate of μ found by using the methods of Section 7-2.
c. Compare the results.
