Statistics

[Nataly]

I have this statistics question for you guys:

The weights six aspririn pills (mg)

1- 324.0
2- 324.6
3- 325.9
4- 342.2
5- 324.2
6- 325.8

A) find standard deviation (I've got this part)

B) Use the standard deviation obtained in part A to estimate the variation in the number of pills that could be produced from 2000.0 kg of aspirin.

I'm kinda stuck on part B. Do you have any suggestions?

Thanks!

Unfortunately, you did not share with us your results.

Mean = M
Standard Deviation = SD

You supply the numerical values.

Let's use 3 Standard Deviations as a nicely inclusive estimate of extremes.

Highest Possible Mass = M + 3*SD
Least Possible Mass = M - 3*D

Least Number of Pills = 2000 / (Highest Possible Mass)
Greatest Number of Pills = 2000 / (Least Possible Mass)
