A recent study was conducted to determine the concentration of lead in drinking water across various states. 25 water samples fr
om the state of Washington were tested; the mean lead concentration was found to be 0.15%. This compares to 32 water samples in the state of Minnesota where the mean was reported to be 0.21%. The data was calculated to be significant at the 0.0001 level. Determine the meaning of this significance level.
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.
