Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFदिया गया है:
n = 6
p = 1/4
सूत्र:
Sk = (1 - 2p)/√(np(1 - p)
गणना:
X की विषमता = (1 - 2 × 1/4)/√(6 × 1/4(1 - 1/4)
⇒ (1 - 1/2(/√(3/2 × 3/4
⇒ 1/2/√(9/8)
∴ X की विषमता का मान √2/3 है।
द्विपद बंटन = एक यादृच्छिक चर X का द्विपद बंटन होता है, यदि इसका प्रायिकता बंटन निम्न द्वारा दिया जाता है
b(x; n, p) = P(X = x) = (n x)pxqn - x x = 0, 1, 2, ----n
सामान्य वितरण में प्रायिकता घनत्व फ़लन द्वारा दिया गया है
f(x) = [1/(σ√2π)]e1/2(x - μ/σ)2
यहाँ, μ और σ इस वितरण के प्राचल हैं। प्राचल μ माध्य है और इस वितरण के विचरण का वर्गमूल σ है
-∞ < μ < ∞, σ > 0
प्रसामान्य बंटन को गाऊसीय वितरण भी कहा जाता है।
