A researcher wants to test the hypothesis that  30 % of the people living  in a certain city are of Hispanic origin , while another 30 % are Afro-Americans , another 30 % are Caucasian and the rest are of other ethnicities . For that purpose he surveyed 500 randomly selected people from the aforementioned city and obtained the following results : Ethnicity  Hispanic Caucasian  Afro-Americans  Others Frequency  120 180 100 100 What is the  critical value of the rejection region used to test the above hypothesis ? ( Round to two decimal places) Use alpha = 0.05

  Below is some partial output for a simple linear regression model that relates sepal width (X) to sepal length (Y) for the iris setosa flower, based on data collected by the famous statistician Sir Ronald Fisher. Measurements are in centimeters:   Pearson correlation of X and Y = 0.701 P-Value = 0.000   Predictor     Coef  SE Coef     T      P Constant    2.7330   0.3429  7.97  0.000 X          0.66111  0.09903  6.68  0.000   Y= 2.7330 +0.66111 X S = 0.258174   R-Sq = 0.492   Sepal width and sepal length are: 

A coffeehouse wishes to see if customers have any preference among 5 different brands of coffee. A sample of  customers provided the data below.

The following table lists the price and number of pages for each of 15 books that were reviewed in the February 1982 issue of the journal Technometrics. Also summary statistics, sample correlation and a scatterplot of the data are shown: Pages Price (in dollars) 302 30 425 24 526 35 532 42 145 25 556 27 426 64 359 59 465 55 246 25 143 15 557 29 372 30 320 25 178 26           Pearson correlation of Pages and Price (in dollars) = 0.401 Find the coefficient of determination ( as a decimal ) . Round to two decimal places  

The following set of data is randomly selected from a STA 2122 class of mine from spring 2010.The list includes clicker points earned in class (clickers allow students to answer questions in classand to have their answers scored) and their final averages.   Clicker points 32 11 34 41 16 Class Average 99 70 91 101 79  Find the correlation coefficient ( round to two decimal places)
