Answer:
The answer is "94"
Step-by-step explanation:
Given data:
51,54,64,68,72,74,76,83,94,94,99
Find:
[tex]P_{75}=?P_{75}= (\frac{75(n+1)}{100})^{th} \ \ observation\\\\[/tex]
[tex]= (\frac{75(11+1)}{100})^{th} \ \ observation\\\\= (\frac{75(12)}{100})^{th} \ \ observation\\\\= (\frac{75 \times 12}{100})^{th} \ \ observation\\\\= (\frac{900}{100})^{th} \ \ observation\\\\= 9^{th} \ \ observation\\\\= 9^{th} \ number \ is = 94[/tex]
