- Answer the following questions : 10\times5=50 नीचे दिए गए प्रश्नों के उत्तर दीजिए : Suppose the events A_1, A_2, \cdots, A_n are independent and that (a) P(A_i) = \frac{1}{i+1} for 1 \le i \le n. Find the probability that none of the n events occur. माना कि घटनाएँ A_1, A_2, . . , A_n स्वतंत्र हैं और P(A_i) = \frac{1}{i+1} जहाँ 1≤i≤n. कोई भी n घटना के घटित न होने की प्रायिकता ज्ञात कीजिए। If X is a Poisson variate with parameter m, then show that a standard Poisson (b) variate tends to standard normal variate as m \rightarrow \infty. Find the m. g. f. of this variable. यदि X प्राचल m सहित एक प्वासों चर है, तो दर्शाइए कि m \rightarrow ∞ होने पर एक मानक प्वासों चर मानक प्रसामान्य चर की ओर प्रवृत्त होता है।
- इस चर का आघूर्णजनक फलन ज्ञात कीजिए। If X_1, X_2, \dots, X_n is a random sample of size n from N(\mu, \sigma^2), where \mu is (c) known and if T = \frac{1}{n} \sum_{i=1}^{n} |X_i - \mu| examine if T is unbiased for \sigma. If not, obtain an unbiased estimator of \sigma. (1) 20/FI-F/CC/M-2023-46/508 (Turn Over)
