14 15 16 17 18 19 Speed(mps/day) 15 3) The puter programming emulation simulation: Based on the given information in the questions, it can be inferred that the numerical value of Y must be larger than or equal to 18, because some of the tourist groups will spend 18 nights on the river. Therefore, the numerical value of Y will be simulated from 18. After that, the programming data are to be ordered. Results of the location simulating program (partial), the codes are in the enclosed table: Team 13544 Page 7 of 22 Computing results of the frequencies of camping (partial), the codes are in the enclosed table: 4) Results of the frequencies of camping The frequencies of camping are displayed in the table: Camp_sim_num Ideal camping scheme 6 7 8 9 10 11 12 13 14 15 16 17 18 18 9 9 9 18 18 18 18 18 18 18 18 18 18 19 9 9 9 9 19 19 19 19 19 19 19 19 20 6 10 10 10 20 20 20 20 20 20 20 20 20 21 7 10 10 10 10 21 21 21 21 21 21 21 21 22 7 11 11 11 11 22 22 22 22 22 22 22 22 Team 13544 Page 8 of 22 23 7 7 11 11 11 11 23 23 23 23 23 23 23 24 8 8 12 12 12 12 24 24 24 24 24 24 24 25 8 8 12 12 12 12 12 25 25 25 25 25 25 26 8 8 8 12 12 12 12 25 25 25 25 25 25 27 6 8 8 13 13 13 13 13 26 26 26 26 26 28 7 9 9 14 14 14 14 14 28 28 28 28 28 29 7 9 9 9 14 14 14 14 14 29 29 29 29 30 7 10 10 10 15 15 15 15 15 30 30 30 30 31 7 7 10 10 15 15 15 15 15 15 31 31 31 32 8 8 10 10 10 16 16 16 16 16 32 32 32 33 8 8 11 11 11 16 16 16 16 16 16 33 33 34 6 8 11 11 11 17 17 17 17 17 17 34 34 35 7 8 8 11 11 11 17 17 17 17 17 17 35 36 7 9 9 12 12 12 18 18 18 18 18 18 36 37 7 9 9 12 12 12 18 18 18 18 18 18 18 38 7 9 9 12 12 12 12 19 19 19 19 19 19 39 7 7 9 9 13 13 13 19 19 19 19 19 19 40 8 8 10 10 13 13 13 20 20 20 20 20 20 41 6 8 10 10 13 13 13 13 20 20 20 20 20 42 7 8 10 10 14 14 14 14 21 21 21 21 21 43 7 8 10 10 10 14 14 14 21 21 21 21 21 44 7 8 8 11 11 14 14 14 14 22 22 22 22 45 7 9 9 11 11 15 15 15 15 22 22 22 22 5） Obtaining the result by using the SPSS software analysis Using the SPSS analyzing software, we can obtain the result through liner fitting. sig Unstandardized Coefficients Adjusted R Square k constant Std. Error ideal Team 13544 Page 9 of 22 ① We can find from the value of Sig. in different coefficients that when the number of campsites is between 37 and 46, all values of Sig. are 0. At that time the fitting coefficient has the greatest significance. And from the adjusted R square we can find that when the number is between 37 and 46, the fitting effect is pretty good. ② Cam: the number of campsites Squ: Squared Euclidean distance Cons: constant Std: Std. Error of k and constant Observe the above table, first we can pare the Squ, the smaller it is, the better the result will be. So the situations of 40, 42, 43, 44, 45, and 46 shall be excluded, in the table are shown in red. After that the situations of 37 and 38 can be excluded through the parison between the actual and ideal efficiency (namely and。 the nearer, the better), and in the table they are shown in blue. At last, we can pare Std. (the smaller, the better), and the situation of 41 can be excluded, in the table are shown in green. Consequently, when the number of the campsites is 39, we can obtain the optimized result. ③ Using spss to analyse , when the number of campsites is 39 ,the result is as follows: camp39 Linear Model Summary Team 13544 Page 10 of 22 R R Square Adjusted R Square Std.

To Determine the Camping program Prerequisite: starting point and end point of the river is not suppose to camp, and the distance of each camp is equal in between which is miles. Number those campsites from the starting point of the river, which are 139 1. The first step, work out the best camping place. Make use of the 39 campsites, and arrange the best camping place. Steps: ① we camp for X nights, which means that we relax in X campsites. The total days staying on the river is X+1. As time goes on, the position of camp in the Nth day accordingly is as follows (the distance between the starting point) Team 13544 Page 12 of 22 ② According to the dis。
