A magazine provided results from a poll of 1500 adults who were asked to identify their favorite pie. Among the 1500 respondents, 14% chose chocolate pie, and the margin of error was given as ±5 percentage points. Wha values do p, q, n, E, and p represent? If the confidence level is 95%, what is the value of a? The value of p is the sample proportion. The value of q is found from evaluating 1-p. The value of n is the sample size. The value of E is the margin of error. The value of p is the population proportion. If the confidence level is 95%, what is the value of a? a =(Type an integer or a decimal. Do not round.)

Average

In mathematics, everyone must have heard the term average in one place or other. Almost all types of calculation require taking out an average. In everyday life, the term is used for denoting a certain amount that can be said to be a typical quantity for multiple people or objects. In other words, if a group of people possesses a certain object, then the average gives us an idea regarding the quantity of the object possessed by each person. However, this is solely based on mathematical calculation. It is important to note that most people will not strictly have the average value in a group.
