In constructing a 90% confidence level estimate of the mean when the population standard deviation (σ) is known what will be your z score used in the formula? HINT: Be sure to review page 236 "Finding Z scores from Known Areas - Special Cases" and Tabel A-2. If you identified it as 1.64 contact me in the DB and I will provide partial credit. Please see my lecture "CIE of the mean z and t examples 2015" as to an...

AS YOU PLAN OUT YOUR ANALYSIS PROJECT, ANSWER ONE OF THE FOLLOWING QUESTIONS: 1.What type of sampling do you plan to use? If you're not sure, what type would you like to use, if possible, and why? 2.What types of statistics will you use to describe your sample? What variables will you use? For example, you will provide the mean and standard deviation for age, frequency distribution by gender and disability status. 3.Did you find anything confusing about probability? If...
