Detailed Solution
Download Solution PDFदिलेल्याप्रमाणे:
'n' निरीक्षणाचा अर्थ आहे
संकल्पना:
मध्यकाची संकल्पना
वापरलेले सूत्र:
सरासरी = बेरीज/एकूण
गणना:
'n' निरीक्षणांची बेरीज = \(n\bar x\)
जेव्हा 'n + 1' आणि '2n - 3' जोडले जाते तेव्हा निरीक्षणांची बेरीज = \(n\bar x + \left( {n + 1} \right) + \left( {2n - 3} \right) = \left( {n + 2} \right)\bar x\)
\(\begin{array}{l} n\bar x + 3n - 2 = n\bar x + 2\bar x\\ \Rightarrow 3n - 2 = 2\bar x \end{array}\)
\(\Rightarrow n = \frac{{2 + 2\bar x}}{3}\)Last updated on May 29, 2025
