Vocabulary How is a ratio table used to graph equivalent ratios? A: The first value in the ratio table always shows the number that is the slope of the line to be graphed.
B: The last value in the ratio table can always be used to find the y-intercept of the line to be graphed.
C: The values in the ratio table are used to write coordinate pairs for points on the graph.
D: The values in the ratio table can be multiplied by the slope of the line to find points on the graph.

C

Step-by-step explanation:

a) The population under consideration in the data set is "adults in the United States".

b) The parameter being estimated is the proportion of adults in the U.S. that could not cover a $400 unexpected expense without borrowing money or going into debt.

c) The point estimate for the parameter of the population is p-hat.

d) The standard deviation of the sampling distribution

e)

f) Yes, 50% is a value not probable if the estimations are right.

g) No, it does not change.

Step-by-step explanation:

f) We can calculate the plausability of the value 50% with our estimations.

The P-value of a proportion of 50% is very low, so the value should surprise.

g) We re-calculate with p=0.4
