A magazine provided results from a poll of 500 adults who were asked to identify their favorite pie. Among the 500 respondents, 11% chose chocolate pie, and the margin of error was given as plus or minus5 percentage points. What values do ModifyingAbove p with caret, ModifyingAbove q with caret, n, E, and p represent? If the confidence level is 99%, what is the value of alpha?

The value of α is 0.10.

Step-by-step explanation:

The (1 - α)% confidence interval for population proportion is:

  OR  

The information provided is:

n = 500

= 0.11

E = ± 0.05

In the (1 - α)% confidence interval for population proportion the variables are defined as follows:

= sample proportion of people who chose chocolate pie

= sample proportion of people who did not choose chocolate pie

n = sample selected for the poll

E = margin of error for the  (1 - α)% confidence interval

p = population proportion of people who chose chocolate pie

The confidence level used is, 99%.

Compute the value of α as follows:

Thus, the value of α is 0.10.

14.3

step-by-step explanation:

add all the numbers together.

9 + 12 + 15 + 16 + 17 + 17 = 86

now, divide 86 by how many numbers we have: 6.

86 / 6 = 14.3

graph them on a graphing calculator, press 2nd trace. select intersect. hit enter until it says answer. ti 84 works best
