Q1.

(c) Yields of wheat for three years are as follows :
Year (X) : 1 2 3
Yield (Y) : Y1 Y2 Y3
Obtain a test for the hypothesis H0: βYX = 0 against H1: βYX ≠ 0, where α = 0.05 and βYX is the regression coefficient of Y on X. गेहूँ की तीन वर्षों की उपज निम्नलिखित हैं:
वर्ष (X) : 1 2 3
उपज (Y) : Y1 Y2 Y3
परिकल्पना H0: βYX = 0 का परीक्षण H1: βYX ≠ 0 के विरुद्ध ज्ञात कीजिये, जबकि α = 0.05 तथा βYX, Y का X पर समाश्रयण गुणांक है।

(d) Describe run test for randomness with examples. उदाहरणों के साथ यादृच्छिकता के लिए रन परीक्षण का वर्णन कीजिये ।

(e) Under what conditions the inequality becomes an equality in case of Cramer Rao lower bound ? Explain it and cite an example. क्रेमर राव निम्नतम प्रतिबन्ध में असमता किन परिस्थितियों में समता बन जाती है ? इसे समझाइये तथा एक उदाहरण दीजिये ।

Q2.

(a) Four unbiased coins are tossed simultaneously. Find the probability of getting exactly three tails if it is known that first toss is a tail. चार अनभिनत सिक्के एक साथ उछाले जाते हैं। अगर यह ज्ञात है कि पहले सिक्के पर पट (टेल) है, तो तीन पट (टेल) मिलने की प्रायिकता ज्ञात कीजिये ।

(b) Let Y have the probability function fY(n) = \binomn + r-1n pr qn; n = 0, 1, 2, ..., p > 0, p + q = 1, show that T = \((r-1))/(r + y-1)\ is an unbiased estimator of p. माना कि Y का प्रायिकता फलन fY(n) = \binomn + r-1n pr qn; n = 0, 1, 2, ..., p > 0, p + q = 1, दिखाइये कि T = \((r-1))/(r + y-1)\, p का अनभिनत आकलक है।
