Generally the sample size is mathematically represented as

[tex]n = 40 + 53 + 65+ 73 + 63 + 70 + 32+ 16[/tex]

=> [tex]n = 412[/tex]

Generally the number of the sample with an income greater $60,000 is mathematically represented as

[tex]N = 63 + 70 + 32 + 16[/tex]

=> [tex]N = 181[/tex]

Generally the number of families with an income more than $60,000 who might or might not purchase a newspaper subscription is

[tex]X = 70[/tex]

Generally the percentage of families with an income more than $60,000 who might or might not purchase a newspaper subscription is

[tex]P(X) = \frac{70}{181} * 100[/tex]

=> [tex]P(X) = 39\%[/tex]
