Answer:
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:
a)=251.2 cm b)=50240 cm
Step-by-step explanation:
a) The formula for calculating the circumference of a circle is c=d*pie, where D is the diameter of the circle.
Therefore, C = 2 * 40 * 3.14 = 251.2 cm
b) The distance covered by 200 revolutions of the wheel is 200 times the circumference, 200*251.2=50240 cm.So to think about this we can assume that there is a point A on the wheel, the distance that point A travels when it rotates 200 times.

Answer:
10/37.
Step-by-step explanation:
The probability that he or she is a management major is 10/37.
The concept of probability that was used was:
Classical probability: The probability is equal to (number of favourable cases) / (number of total cases). Since the total of students who are a management major is 10 and we have 37 students in total, the probability will be 10/37.
