Question

Quality control is an important issue at ACME Company, which manufactures light bulbs. Totest the life-hours of their light bulbs, they randomly sampled nine light bulbs and measured how many hours they lasted: 378, 361, 350, 375, 200, 391, 375, 368, 321. What is the mode

Answer 1

Answer:

Md: 375

Step-by-step explanation:

Hello!

The mode is a measure of central tendency that indicates the value with most absolute frequency, i.e. the most observed value of the variable.

You have the information of the lifespan of 9 randomly sampled lightbulbs, to know the value of the mode you have to check wich lifespan is most repeated:

378, 361, 350, 375, 200, 391, 375, 368, 321

As you can see the only lifespan observed more than once is 375hs, this corresponds to the mode of the data set.

I hope this helps!

Answer 2

Answer:

375

Step-by-step explanation:

The mode of a set of given data value is the value of the data in the given set that appears the most in the given set of data ( most frequent value ).

as seen in the randomly sampled value : 378, 361, 350, 375, 200, 391, 375, 368, 321

The value : 375 is the mostly repeated value in the given set of data above hence the mode recorded is 375 hours

ACME company carrying out quality control on its light bulbs is one way to test how long their product ( light bulbs ) will last when used by an end consumer and also on how to improve the life span of the light bulbs.
