The ages of undergraduate students at two universities (one in the east and one in the west) are being compared.  Researchers want to know if there is a difference in the mean age of students at the two universities.  The population standard deviations are known. The following data shows the results of samples collected at each institution:              School Location       n (sample size)        sample mean ( )         population standard deviation              West                      33                           25.78                       6.29              East                       35                           23.16                       7.52   What is the value of the test statistic for the previous problem?  (Enter your answer as a positive value even if you calculated a negative test statistic value i.e. if you calculated -1.311 you should enter 1.311).  Round your answer to 3 decimal places.

Question 3 Match the questions with answers. Use this sample data for all questions: Table 2: Time taken in seconds. Sample 290, 340, 150, 300, 200, 100, 400, 500, 600, 89, 94 What is the mean for table 2? A. 278.45 What is the median for table 2? B. no mode v What is the mode for table 2? C. 172.06 v What is the sample standard deviation for table2 ? D. -0.46 Calculate the 75th percentile for table 2. E. 622.58 v What is the interquartile range for table 2? F. 290.00 What is the z score for an x value of 200 using table 2? G. 0.46 v Using the empirical rule to find the range of values containing 95% of the data from table 2, what is the upper value of the range?

Consider the following sample data. Sample A: 11, 22, 33 Sample B: 81, 92, 103 Sample C: 1,100; 1,111; 1,122   (a) Find the mean and standard deviation for each sample.    Sample A: Sample B: Sample C: Mean       Sample Standard Deviation          (b) What does this exercise show about the standard deviation?  multiple choice The idea is to illustrate that the standard deviation is not a function of the value of the mean. The idea is to illustrate that the standard deviation is a function of the value of the mean.
