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
