Question: solve the following....

Breathing Rates Is your breathing rate typical? As a matter of fact. there is no standard breathing rate for people. It can differ from as low as 4 breaths each moment to as high as 70 or 75 for an individual occupied with difficult exercise. Assume that the resting breathing rates for school age understudies have a relative recurrence dispersion that is hill molded, with a mean equivalent to 12 and a standard deviation of 2.3 breaths each moment.

What part, all things considered, would have breathing rates in the accompanying spans? a. 9.7 to 14.3 breaths each moment b. 7.4 to 16.6 breaths each moment c. More than 18.9 or under 5.1 breaths each moment

Mineral Examples A geologist gathered 20 diverse metal examples. generally a similar weight, and arbitrarily isolated them into two gatherings. She estimated the titanium (Ti) substance of the examples utilizing two distinct strategies.

Technique 1 Strategy 2 .011 .013 .010 .013 .015 .011 .014 .012 .011 .012 .016 .017 .013 .012 .014 .015

a. Build stem and leaf plots for the two informational indexes. Outwardly think about their focuses and their reaches.

b. Compute the example means and standard deviations for the two sets. Do the determined qualities affirm your visual determinations from section a?

Question 45

Government backed retirement Numbers A gathering of 70 understudies were approached to record the last digit of their government backed retirement number.

1 6 9 1 5 9 0 2 8 4 0 7 3 4 2 3 5 8 4 2 3 2 0 2 1 2 7 4 0 9 5 3 8 4 7 4 6 9 0 2 6 2 9 5 8 5 1 7 8 7 5 1 8 3 4 1 9 3 8 6

a. Draw an overall recurrence histogram utilizing the qualities 0 through 9 as the class midpoints. What is the state of the circulation? In view of the shape, what might be your best gauge for the mean of the informational index?

b. Utilize the reach estimate to figure the estimation of s for this set. c. Utilize your adding machine to track down the real qualities .Contrast and your evaluations in parts a and b.

Problem 1: 15 points = [5 + 5 + 5] A small hair dresser shop operates with three hair stylists. It has two waiting seats so that when new customers arrive and all stylists are busy and there is no vacant seat, they leave. The state space S of this "birth-and-death" process is S = {0, 1, 2, 3, 4,5} . where r E S indicates the number of customers either waiting or having the ongoing service. When 1 5. 1. Derive the stationary distribution for a number of customers in the shop. 2. Determine the limiting probability of the idle state, a = 0, that is: lim P [X (t) = 0] 1-+00 3. Determine the limiting probability of losing customers because the shop is full, that is: lim P [X (t) = 5] 1-1006.4.5 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 or is a reaction rate of formation. Suppose also that in any small time interval of length h, 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(t) denote the number of AB molecules at time r. Model X(t) as a birth and death process by specifying the parameters.The objective of a research study is to nd the impact of work stress, employee motivation and team work on organizational commitment of employees in IT firms in Karachi. The results of regression analysis are provided in Table 1: Tablei Results of Regression Analysis You are required to: a. Interpret the results of regression analysis. { 6 Marks] 1:). Compose a regression equation. (2 Marks] In a population, the birth rate and death rate are calculated as follows: Birth Rate = Number of Elirths : Population Death Rate = Number of Deaths + Population For example, in a population of IDDDUD that has EDDIE births and 6,1300 deaths per year, the birth rate and death rate are: Birth Rate = EDDIE! + IDUDUD = (1.133 Death Rate = HEIDI] + l = 0.06 Design a Population class that stores a population, number of births, and number of deaths for a period of time. Member functions should return the birth rate and death rate. Implement the class in a program. Input 1|lialidation: Do not accept population figures less than 1, or birth or death numbers. less than t]
