Example 5: A corporation psychologist believes that exercise affects self image. To investigate this possibility, 14 employees of the corporation are randomly selected to participate in a jogging programme. Before beginning the programme, they are given a questionnaire that measure self-image. Then they begin the jogging programme. The programme consists of jogging at a moderately taxing rate for 20 minutes a day, 4 days a week. Each employee's self-image is measured again after 2 months on the programme. The results are shown below (the higher the score, the higher the self-image); a score of 20 is the highest score possible.

A golfer practices different parts of their game for hours. Specifically, the golfer practices:(1) putting, (2) their short game, and (3) their iron game. The amount of time spent on each partof their game is exponentially distributed. If the golfer is practicing their putting, they will alwaysswitch to their short game after an average of 30 minutes. When the golfer practices their short game,they do so for an average of 45 minutes, and then switches to putting with probability 0.6 or to theiriron game with probability 0.4. When they practice their iron game, they do so for an average of 60minutes. After practicing their iron game, the golfer will switch to putting or to their short game withequal probability.(a) Draw the CTMC rate diagram, clearly label your states and transition rates (qij ’s)(b) Find the transition rates out of the states (vi’s) and transition probabilities (Pij ’s).(c) Find the limiting probabilities (make sure to write out the balance equations).(d) In the long…

A suggested model to describe the population over time is: P= L 1+ e-k(x-xo) Where p is the population, x is the year and L, k and x, are constants. I represents the all time maximum of the population. a) Fit the model to the data using non-linear regression using initial guesses L = 20, k = 0.01 and x) = 2050. What will be the all time maximum of the world population according to this model? b) Find the coefficient of determination (R²) for the fit. (If you did not answer question a), you may use the initial guesses as parameter values).
