Which of the following numbers would be an outlier if added to the data set below?
1 answer:
Answer:
406,209,308
According to their deviation from the mean 350.25
Step-by-step explanation:
To Know an outlier we'll determine it by looking for the mean of the data set first then checking the deviation of the numbers each from the mean.
Mean = (372+351+299+406+387+315
+364+308)/8
Mean =2802/8
Mean= 350.25
Ok now let's determine the deviations
372 - 350.25= 21.75
351 - 350.25= 0.75
299- 350.25= -51.25
406 - 350.25= 55.75
387 - 350.25= 36.75
315- 350.25 = -35.25
364- 350.25= 13.75
308- 350.25= -42.25
According to the magnitude of the deviation 406 and 299 has the highest deviation so they are the outliers followed by 308

Answer:
130
Step-by-step explanation:
So you have 780 and 6 right? So, you put 780 in the division box and 6 right outside. Divide and you will get 130, unless you make a mistake.
