Exercise 5 For all-natural number n, we define I, = F sin" x dx i.) a.) Calculate l, and /4. n+1 b.) Show that In+2 In n+2 c.) Show that (I,) is a positive decreasing sequence. d.) Using the preceding results, show that n+2 n+1 < !n+1 < 1. Hence, calculate the limit of 1. In ii.) We define the sequence t, = (n + 1)/n+1!n- a.) Show the sequence (t,) is a constant sequence. b.) Deduce that for all n, tn = iii.) We define v, = nl. a.) Express vn in terms of n, tn, In and In+1. Hence, calculate the limit of v. b.) Deduce the limit of nl. %3D iv.) a.) Calculate S sin 3x dx. 22 (nl)? (2n+1)! T(2n): b.) Show that In = and that I2n+1 = 22+ (n!)?
Contingency Table
A contingency table can be defined as the visual representation of the relationship between two or more categorical variables that can be evaluated and registered. It is a categorical version of the scatterplot, which is used to investigate the linear relationship between two variables. A contingency table is indeed a type of frequency distribution table that displays two variables at the same time.
Binomial Distribution
Binomial is an algebraic expression of the sum or the difference of two terms. Before knowing about binomial distribution, we must know about the binomial theorem.
