Answer:
14110
Step-by-step explanation:
Let x = number of pages;
μ = 12200; σ = 820
Zscore = (x - μ) / σ
Zscore = (x - 12200) / 820
Zcritical for 99% confidence, with a one-tailed test equals 2.33
Hence, Z at 99% = 2.33
Substituting in for Zscore = 2.33
Zscore = (x - 12200) / 820
2.33 = (x - 12200) / 820
2.33 * 820 = x - 12200
1910.6 = x - 12200
1910.6 + 12200 = x
x = 14110.6
x = 14111
The number of pages to advertise for the cartridge is 14,110
Answer:
The earnings gap, over a career spanning 30 years, between men and women totals $1,200,150
Step-by-step explanation:
Calculated annually.
The typical male earns $90,761 each year.
The typical female earns $50,756 per annum.
Therefore, the annual difference is:
90,761 - 50,756 = 40,005
Across 30 years:
30*40,005 = 1,200,150
The earnings gap over a 30-year career, when comparing men and women, is $1,200,150
