When is at a significance level of 0.0001, the concentration of lead is above in water from Minnesota.
Step-by-step explanation:
The Significance level is the calculation or estimation of the strength of proof that must be seen in a sample, before the hypothesis will be rejected and concluded that the result is statistically true or correct.
In this case, when a data is calculated to be significant at 0.0001 from a recent duty, what the significance level implies in this case is that, at a level of 0.001, the concentration of lead is above or higher in water from Minnesota.

Answer:
58.5 mg
Step-by-step explanation:
Drink: 130% of RDA of vitamin X
RDA vitamin X = 45mg
130% of 45 = mg in the drink
