08:55:39 `qNote that there are four questions in this assignment. `q001. Recall the stock value problem, where March, July and December values were $5000, $5300 and $5500. Construct a graph of stock value vs. number of month (e.g., 1 for Jan, 2 for Feb, etc.). You will have three points on your graph, one corresponding to the March value, one to the July value, and one to the December value. Stock value will be on the y axis and month number on the x axis. Your first point, for example, will be (3, 5000), corresponding to $5000 in March. Connect your three points with straight lines--i.e., connect the first point to the second and the second to the third. What is the slope of your line between the first and second point, and what is the slope of your line between the second in the third point? Recall that slope is rise / run.

RESPONSE --> point 1 to point 2 slope = 75 point 2 to point 3 slope = 40 confidence assessment: 2

09:03:51 `q003. To what extent do you think your graph, consisting of 3 points with straight line segments between them, accurately depicts the detailed behavior of the stocks over the 9-month period?
......!!!!!!!!...................................
RESPONSE --> the slope of a line will give you a fairly good look at what the avg. rate of change. overall the points show an obvious trend however more points on the graph would show a more detailed anaylsis of the data such as outlying points. confidence assessment: 2

09:04:20 Stocks can do just about anything from day to day-they can go up or down more in a single day than their net change in a month or even a year. So based on the values several months apart we can't say anything about what happens from day to day or even from month to month. We can only say that on the average, from one time to another, the stocks changed at a certain rate.

09:07:46 `q004. From the given information, do you think you can accurately infer the detailed behavior of the stock values over the nine-month period?
......!!!!!!!!...................................
RESPONSE --> no, stocks fluxuate on a day to day basis and only having 3 points over a nine month period is not enough data to acurately infer the data. confidence assessment: 3
.................................................
......!!!!!!!!...................................
09:07:57 Not on a day-to-day basis, and not even on a month-to-month basis. All we can see from the given information is what might be an average trend.
