Question
c. Suppose the correlation between total number of Internet users and? cell-phone users differs from that of Internet use and? cell-phone use. Explain why this difference might exist. Choose the correct answer below.
A.
The Internet is used more than? cell-phones.
B.
The total number of Internet users is different than the total number of? cell-phone users.
C.
Some Internet users may use the Internet more or less than others.? Likewise, some? cell-phone users may use their? cell-phones more or less than others.
D.
Most Internet users use the Internet the same amount as others.? Likewise, most? cell-phone users use their? cell-phones the same amount as others.
For a table of national information it is found that the correlation with Internet use is 0.553 for GDP, 0.817 for cellular-phone use, 0.604 for literacy, 0.716 for fertility, and 0.624 for CO2 emissions. Use this information to answer parts a through c. a. Which variable has the strongest linear association with Internet use? O A. GDP has the strongest linear association with Internet use B. CO2 emissions has the strongest linear association with Internet use. ° C. Fertility has the strongest linear association with Internet use ( D. Literacy has the strongest linear association with Internet use. 0 E. Cellular-phone use has the strongest linear association with Internet use b. Which variable has the weakest linear association with Internet use? A. Fertility has the weakest linear association with Internet use O B. Literacy has the weakest linear association with Intemet use. O C. Co2 emissions has the weakest linear association with Internet use. o D. GDP has the weakest linear association with Internet use. O E. Cellular-phone use has the weakest linear association with Internet use. c. Suppose the correlation between total number of Internet users and cell-phone users differs from that of Internet use and cell-phone use. Explain why this difference might exist. Choose the correct answer below.Explanation / Answer
|r| is the highest for cell phone.
Hence cell phone has the strongest correlation with internet use.
-----------------------------------------
Weakest is one which has least |r|
Hence 0.553 is the least abs value.
GDP has the weakest association with internet usage.
--------------------------------------------------
C.
Some Internet users may use the Internet more or less than others. Likewise, some cell-phone users may use their cell-phones more or less than others.
