A. At one time during his term, President Bush's approval rating was 41 percent with a margin of error of plus or minus 3 points. Write this statement as a
confidence interval.
B. The article does not state the confidence level for the ratings. Use the margin of error to determine the standard error of the estimate (standard
deviation) if a 95% confidence level was used. What is the standard error if a 99% confidence level was used?

b. 6

step-by-step explanation:

we are given the table representing an exponential function.

we can see from the table that, as x is increasing, the value of y is increasing in the power of 6.

i.e. the following relation is obtained,

x = 1, y = 6

x = 2, y = 36 =

x = 3, y = 216 =

x = 4, y = 1296 =

x = 5, y = 7776 =

so, the geometric series obtained is .

thus, the common ratio is given by = = 6.

hence, the common ratio is 6.
