Question
I know the answer of question a , mean=369.83, median=367.5, standard deviation=25.087, what i need to know is the answer for question b.
A sample of 24 offshore oil workers took part in a simulated escape exercise, resulting in the accompanying data on time (sec) to complete the escape: 370 364 366 364 325 339 393 355 359 363 375 424 325 394 402 392 369 374 359 356 403 334 397 a. Calculate the values of the sample mean and median and sample standard deviation. Sample mean Sample median Sample standard deviation*- b. By how much could the largest time, currently 424, be increased without affecting the value of the sample median? By how much could this value be decreased without affecting the value of the sample mean?Explanation / Answer
the largest value 424 do not have any effect over median you can increse or decrease by any margin.
where as the sample mean value changes even a slight change in 424 value
424 value should remains same without any increase or decrease to maintain sample mean constant
