Answer:
A one-tailed hypothesis will be used to perform the test.
Step-by-step explanation:
The purpose of the marketing research consultant hired by Coca-Cola is to determine whether the the proportion of customers who prefer Coke to other brands is over 50%.
The marketing research consultant selected a random sample of <em>n</em> = 200 customers. The sample proportion of people who favored Coca-Cola over other brands was 55%.
The marketing research consultant can perform a single proportion hypothesis test to determine whether greater than 50% of customers prefer Coca-Cola to other brands.
Since we need to determine whether the population percentage is greater than a null value, the hypothesis is not two-tailed.
The hypothesis can be defined as:
<em>H₀</em>: The proportion of people who favor Coca-Cola over other brands was 55%, i.e. <em>p</em> = 0.50.
<em>Hₐ</em>: The proportion of people who favor Coca-Cola over other brands was more than 55%, i.e. <em>p</em> > 0.50.
Thus, a one-tailed hypothesis will be used to perform the test.
Answer:
what's the slope?
Step-by-step explanation:
Answer:
y = 3x + 2
Step-by-step explanation:
The shaded region is somewhat going up, and the graph is positive. That leaves 2 answer choices. If you measure the slope by counting the blocks from one point to another by counting up/down from one point to the height to another point, and then go right or left to the other point. the slope is 3, therefore y = 3x +2 is the answer, as it is the only one that the shaded region is above the line and that has a slope of 3. Hope this helps!
Answer:
C. f(x) and g(x) are the same when x = 2
Step-by-step explanation:
FINDING F(X)
If you plug in x = 2 into f(x) = x+ 1, we get the expression:
x + 1
= 2 + 1
= 3
FINDING G(X)
By looking on the graph, we see that g(2) = 3.
Since they both equal 3 when x=2, the answer choice is C: f(x) and g(x) are the same when x = 2.
6 because if you take the 2.04679 then divide you would get 6.
