You are conducting a test of homogeneity for the claim that two different populations have the same proportions of the following two characteristics. Here is the sample data. Category A B Population Population #1 #2 34 46 100 15 What is the chi-square test-statistic for this data? x²

In a test of the difference between the two means below, what should the test value be for a t test? Sample mean Sample variance Sample size 0 -0.25 O -0.09 O -0.12 O-1.93 Sample 1 520 500 9 Sample 2 535 60 12

What are the values for SS and variance for the following sample of n = 3 scores? Sample:  8, 5, 2

Need sub part B answered only

Refer to the table of sample values in Section 8.2 Exercise 10 of the text.Find the values of the UCL and LCL for the  (x-bar) chart for this data, and round your answers to 3 places after the decimal point.

You answered this question: What is the Sample Variance for the following numbers:52, 62, 52, 45, 41

I am having trouble with this one, please help. Thank you
