Instructor: Charles Conrad Course: STATISTICS - 7 WEEK - FALL 2017 Student: keith holden Date: 10/9/17 Assignment: Chapter 10.1 Homework 5. Listed below are numbers of Internet users per 100 people and numbers of scientific award winners per 10 million people for different countries. Construct a scatterplot, find the value of the linear correlation coefficient r, and find the P-value of r. Determine whether there is sufficient evidence to support a claim of linear correlation between the two variables. Use a significance level of = 0.05. Internet Users Award Winners 80.2 5.4 78.6 9.4 57.4 3.3 68.4 1.6 77.8 10.7 38.6 0.1 Construct a scatterplot. Choose the correct graph below. 0 30 90 12 Award Winners 12 C. 0 30 Internet Users D. 12 Award Winners B. Award Winners Award Winners A. 0 30 90 Internet Users 90 Internet Users The linear correlation coefficient r is (Round to three decimal places as needed.) 12 0 30 90 Internet Users . Determine the null and alternative hypotheses. H0 : (1) H1 : (2) (Type integers or decimals. Do not round.) The test statistic is . (Round to two decimal places as needed.) The P-value is . (Round to three decimal places as needed.) Because the P-value of the linear correlation coefficient is (3) the significance level, there (4) sufficient evidence to support the claim that there is a linear correlation between Internet users and scientific award winners. (1) = (2) = > > < < (3) less than or equal to greater than (4) is not is
