Question Help The population of a certain country was studied in an article. The authors examined the different occupations for males and females in the country. The accompanying table is a frequency distribution of occupation type for males taking part in a survey. (Note: Mmanufacturing, N nonmanufacturing.) Complete parts (a) through (d) below EE Click the icon to view the frequencies of occupation type for surveyed males a. Find the probability that a randomly selected male's occupation is clerk. The probability that a randomly selected male's occupation is clerk is (Type an integer or a decimal. Round to three decimal places as needed.) b. Find the probability that a randomly selected male's occupation is technical The probability that a randomly selected male's occupation is technical is (Type an integer or a decimal. Round to three decimal places as needed.) c. Find the probability that a randomly selected male's occupation is manufacturing The probability that a randomly selected male's occupation is manufacturing is (Type an integer or a decimal. Round to three decimal places as needed.) d. Find the probability that a randomly selected male's occupation is not manufacturing The probability that a randomly selected male's occupation is not manufacturing is (Type an integer or a decimal. Round to three decimal places as needed.) i Frequencies of Occupation Types Occupation Administrative/M Administrative/N Technical/M Technical/N Clerk/M Clerk/N Production workers/M Production workers/N Service Agriculture Frequency 2187 6080 2060 6529 1361 4924 5884 10,841 9838

Explanation / Answer

Total frquency = 2187+6080+..... 111 = 49815

a) P( Clerk) = (1361+4924)/49815 = 0.126

b) P( Technical) = (2060+6529)/49815 = 0.172

c) P( manufacturing) = (5884+10841)/49815 = 0.336

d) P( Not manufacturing) = 1-0.336 = 0.664
