She measures the time that it takes to assemble a specific part by 100 people atdifferent shifts and on different days. The record of her study is organized and shown in the table below.Based on data provided, we have calculated the probabilities correspond- ing to the time intervals that people took to assemble the parts.The probability distribution for this example is shown in the table below and the following figure.Data Pertaining to this exampleProbability0.180.160.140.120.100.080.060.040.020.005 6 7 8 9 10 11 12 13 14Time (minutes)Data Pertaining to this exampleTime That It Takes a Person toAssemble the Part (minutes)5Plot of probability distribution for this example.67891011121314Frequency581115171413863Σ = 100Probability(p)0.050.080.110.150.170.140.13Again, note that the sum of probabilities is equal to 1. Also note that if we were to connect the midpoints of time results (as shown in thefigure below), we would have a curve that approximates a bell shape. As the number of data points increases and the intervals decrease,the probability-distribution curve becomes smoother. A probability distribution that has a bell-shaped curve is called a normal distribution.The probability distribution for many engineering experiments is approximated by a normal distribution.0.080.060.03Σp=1

The authors of the paper "Evaluating Existing Movement Hypotheses in Linear Systems Using Larval Stream Salamanders"+ investigated whether water temperature was related to how far a salamander would swim and whether it would swim upstream or downstream. Data for 14 streams with different mean water temperatures where salamander larvae were released are given (approximated from a graph that appeared in the paper). The two variables of interest are x = mean water temperature (°C) and y = net directionality, which was defined as the difference in the relative frequency of the released salamander larvae moving upstream and the relative frequency of released salamander larvae moving downstream. A positive value of net directionality means a higher proportion were moving upstream than downstream. A negative value of net directionality means a higher proportion were moving downstream than upstream. Mean Temperature (x) Net Directionality (y) 6.17 -0.08 8.06 0.25 8.62 -0.14 10.56 0.00 12.45…
