1) critical t values, negative and positive z scores

A magazine provided results from a poll of 500 adults who were asked to identify their favorite pie. Among the 500 respondents, 13% chose chocolate pie, and the margin of error was given as + 3 percentage points. What 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 value of q is The value of n is The value of E is The value of p is If the confidence level is 95%, what is the value of a? a =(Type an integer or a decimal. Do not round.)Assume the readings on thermometers are normally distributed with a mean of OC and a standard deviation of 1.00 C. Find the probability that a randomly selected thermometer reads between - 2.16 and - 1.57 and draw a sketch of the region. Click to view page 1 of the table. Click to view page 2 of the table.

Construct a 99% confidence interval estimate of the mean body temperature of all healthy humans. What does the sample suggest about the use of 98.6 F as the mean body temperature?
