Problem 1) correct
What percentage of the area would the Empirical Rule say is between z = -3.00 and z = +3.00?
Solution

The Empirical rule states that the p
Suppose we want to determine the (binomial) probability (p) of getting 5 heads in 15 flips of a 2-sided
coin. Using the Binomial table in the appendix of the text, what values of n, x, and p would we use to
look up this probability, and what would be the
Assuming a normal distribution, what is the z-score associated with the second quartile?
The second quartile is Q2 which is equal to P50 or 50% or .50. If you are looking for the z score usually
you would just find the closest value to .50 on the normal d
If we wish to have a 95% confidence interval, what would be the value of the confidence coefficient?
The confidence coefficient is also known as the confidence level. The confidence level can be found using
simple steps. If we want a confidence interval o
In hypothesis testing, as the level gets smaller, the level of confidence increases. T or F, and why or
why not?
True.
As the a level gets smaller say from .05 the confidence level is at 95% but if the a level goes to .01 the
confidence level increases to
Question 1
Would you suspect that the IDEA surveys sent to South students each term could be
biased in the responses received? Why or why not?
Response bias refers to the bias that results from problems in the measurement
process. Some examples of respons
