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.
"Rotation and reflection" are the composition of transformations among the following choices given in the question that <span>will map figure K onto figure S and then onto figure U. The correct option among all the options that are given in the question is the second option or option "B". I hope that the answer has helped you. </span>
To find ten percent, you divide by ten. Then multiply that answer by five to get fifty percent. Subtract that answer from the original price. But because this one is fifth you could just divide by two.
Each angle of the equilateral triangle in the figure has measure (2x – 9)°. Determine the value of x. O A. x = 60 O B. x = 25.5 O C. x = 69 O D. x = 34.5
im not 100% sure about this but i think i did this right hope it help man!
