Heloo kindly assist me please to solve The following questions.

The amount Leisure time? When you were growing up, did you feel that you needed more available energy? Guardians and kids have varying sentiments regarding this matter. An examination bunch reviewed 198 guardians and 200 kids and recorded their reactions to the inquiry, "How much spare energy does your youngster have?" or "How much leisure time do you have?" The reactions are appeared in the table below:2

Simply the Not very Don't Perfect Sum Sufficient Much Know

Guardians 138 14 40 6 Kids 130 48 16 6

a. Characterize the example and the number of inhabitants in interest to the analysts. b. Portray the factors that have been estimated in this overview. Are the factors subjective or quantitative? Are the information univariate or bivariate? c. What do the passages in the cells address? d. Utilize near pie diagrams to think about the reactions for guardians and kids. e. What other graphical procedures could be utilized to depict the information? Would any of these procedures be more instructive than the pie outlines developed to some extent d?

Question 53

Purchaser Cost Record The cost of living in the US has expanded significantly in the previous decade, as shown by the shopper cost lists (CPIs) for lodging and transportation. These CPIs are recorded in the table for the years 1996 through the initial five months of 2007.3

Year 1996 1997 1998 1999 2000 2001 Lodging 152.8 156.8 160.4 163.9 169.6 176.4 Transportation 143.0 144.3 141.6 144.4 153.3 154.3 Year 2002 2003 2004 2005 2006 2007 Lodging 180.3 184.8 189.5 195.7 203.2 207.8 Transportation 152.9 157.6 163.1 173.9 180.9 181.0

a. Make next to each other relative bar graphs to portray the CPIs over the long haul.

b. Draw two line diagrams on similar arrangement of tomahawks to depict the CPIs over the long run.

c. What decisions would you be able to make utilizing the two charts in parts an and b? Which is the best?

(2.14) Drifting random walk. Random walks with a constant drift term will have a net correlation between steps. This prob- lem can be reduced to the problem without drift by shifting to a 'moving reference frame'. In par- ticular, suppose we have a random walk with steps independently drawn from a uniform den- sity p(() on [0,1), but with a non-zero mean (0) = 1#0. Argue that the sums s'N = En (en - () describe random walks in a moving reference frame, with zero mean. Argue that the variance of these ran- dom walks (the squared standard deviation ) is the same as the variance ((SN -SN)') of the original random walks.6.4.5 A chemical solution contains A molecules of type A and an equal number of molecules of type B. A reversible reaction occurs between type A and B Continuous Time Markov Chains 315 molecules in which they bond to form a new compound AB. Suppose that in any small time interval of length h, any particular unbonded A molecule will react with any particular unbonded B molecule with probability ah + o(h), where a is a reaction rate of formation. Suppose also that in any small time interval of length /, any particular AB molecule disassociates into its A and B constituents with probability Bh + o(h), where B is a reaction rate of dissolution. Let X(1) denote the number of AB molecules at time r. Model X(/) as a birth and death process by specifying the parameters.{a} Consider an unrestricted simple random walk with p = {1.3 and q = ['31. If the random wall: starts in state ll], what is the probability.r that the walk ever reaches state El}? {b} Consider a simple random walk with p = [1.3 and q = {1.3 and absorbing barriers at 5 and Ell If the random wall: starts in state l, what is the probability that the walk will absorb to the barrier at 5? {c} For the simple random walk in {b}1 a gain of $3 is obtained if the barrier at it} is reached1 while a low of $2 is incmTed if the walk absorbs to the barrier at 5. Determine the expected loss. 1. Which of the following is a true statement for a regression analysis? II regression analysis is applied only to non-linear model II regression analysis is applied only to a multiplicative model regression analysis is applied only to a linear model regression analysis is applied only to an exponential model. 1 Which of the following is not one of the four components of experimental design? -_ -_ -_ -_
