An article gave data on various characteristics of subdivisions that could be used in deciding whether to provide electrical power using overhead lines or underground lines. Here are the values of the variable x = total length of streets within a subdivision:

1280	5320	4390	2100	1240	3060	4970
1050	360	3330	3380	340	1000	960
1320	530	3350	540	3870	1250	2400
960	1120	2120	450	2250	2320	2400
3150	5700	5220	500	1850	2460	5850
2900	2730	1670	100	5770	3150	1890
510	240	396	1419	2109

In this question you are going to calculate the data that could be used to construct a titration curve (pH versus volume of titrant added) for the titration of an aqueous ammonia (NH3; weak base, pKB = 4.7) cleaning solution with a strong acid (HCl). When strong acid is added to an aqueous solution, it immediately reacts and yields H3O + ions; thus the titration is described by the reaction: NH3(aq) + H3O + (aq)  NH4 + + H2O(l)...
