Answer:
The correct option is;
We cannot infer a cause and effect relationship because we do not have a control group
Step-by-step explanation:
The treatment in research involves giving stimulus known as treatment to a group or portion of the sample which are then known as the treatment group while the remaining portion of the the sample are exempted from the stimulus. A successful treatment manipulation is one where members of the treatment group perform higher in the measured metrics of the research than members of the control group.
Given that the researchers gathered data from a random sample of drivers and measurement of several variables including the explanatory variable of the of the research without subjecting a sample to a treatment or having a control group we cannot infer a cause and effect relationship as there are no control group
Answer:
We divide it into 3 rectangles:
A rectangle with sides 19mi and 5mi,
a rectangle with sides 1mi and 31mi,
and a rectangle with sides 10mi and 20mi,
so we get 95 + 31 + 200 = ![\boxed{326}](https://tex.z-dn.net/?f=%5Cboxed%7B326%7D)
Hope this helps!
Given the function, P = 22x - 1200, be the model determining the profit of Henry's new business. Now, the lowest amount that P could generate would be when Henry does not sell any shirt. This gives x a value of 0 and P = 0 - 1200 = -1200.
Now, he can get the highest profit when he gets to sell all of the 600 shirts. Thus, we have x = 600 and P = 22(600) - 1200 = 12000.
Since the minimum and maximum values of P are -1200 and 12000, then the range of P would be {-1200 ≤ p ≤ 12000}.
Answer: D) {-1200 ≤ p ≤ 12000}
Given:
Actual: 9.0 lbs with standard deviation of 0.35 lbs
sample: 8.2 lbs
standard deviation means that the fish caught should be within the range of 8.65 and 9.35
9.00 + 0.35 = 9.35 lbs
9.00 - 0.35 = 8.65 lbs
The sample that had an average weight of 8.2 lbs is not a representative of the population because its weight goes beyond the standard deviation.
