up until the early 1900s, peeps who colored their hair used only herbs and dyes today hair coloring products contain two main ingredients hydrogen peroxide and ammonia. the makers of a clairol hair color product claim that the mean amount of hydrogen peroxide in each bottle is .10 mg/m^3. assume that the standard deviation is .05 mg/m^3 a random sample of these hair-color products was obtained, and the amount of hydrogen peroxide in each bottle was measured. the resulting data in mg/m^3 are:

0.14
0.14
0.11
0.09
0.15

i'm not sure how to calculate this with all that data.
also, is there any evidence that suggests the manufacturer is including too much hydrogen peroxide in the product?

thanks.
