CSU Week 3 Normal Distributions Questionnaire
Problems need to include all required steps and answer(s) for full credit. All answers need to be reduced to lowest terms where possible. If the answer is in %, show two decimal places.Answer the following problems showing your work and explaining (or analyzing) your results. Submit your work in a typed Microsoft Word document.The average score of a statistics class was 71 with a standard deviation of 8.What is the z score of a student with a grade of 68? (2.5 pts)What is the z score of a student with a grade of 80? (2.5 pts)Using the same data in #1 answer the following:Approximately 68% (one standard deviation) of the scores are between ________ and _________ (2.5 pts)Approximately 95% (two standard deviation) of the scores are between _________ and _________ (2.5 pts)Most values of the standard normal distribution are between __________. (3 pts)-3 and 30 and 10 and 31 and 3(a) If the standard deviation of a data set is 1.3, what is the variance? (2.5 pts)(b) If the variance is 36, what is the standard deviation? (2.5 pts)Let X have a normal distribution with mean µ= 20 and standard deviation σ = 4. Determine the area in the normal curve for which:P (X > 28) (2.5 pts)P (X > 12) (2.5 pts)P (X > 24) (2.5 pts)The IQ scores of students listed below are from a SAMPLE of MATH 300 class.
