3. An article in the New England Journal of Medicine, reported about a study of smokers in Californiaand Hawaii. In one part of the report, the self-reported ethnicity and smoking levels per day were given.Of the people smoking at most ten cigarettes per day, there were 9,886 African Americans, 2,745 NativeHawaiians, 12,831 Latinos, 8,378 Japanese Americans, and 7,650 Whites. Of the people smoking 11 to20 cigarettes per day, there were 6,514 African Americans, 3,062 Native Hawaiians, 4,932 Latinos,10,680 Japanese Americans, and 9,877 Whites. Of the people smoking 21 to 30 cigarettes per day, therewere 1,671 African Americans, 1,419 Native Hawaiians, 1,406 Latinos, 4,715 Japanese Americans, and6,062 Whites. Of the people smoking at least 31 cigarettes per day, there were 759 African Americans,788 Native Hawaiians, 800 Latinos, 2,305 Japanese Americans, and 3,970 Whites.a.) Complete the table using the data provided.LatinoNativeHawaiianSmokingLevel1-1011-2021-3031+TOTALAfricanAmericanJapaneseAmericanWhiteTOTALb.)
