In a study to determine the relationship between ambient outdoor temperature and the rateof evaporation of water from soil, measurements of average daytime temperature in °C andevaporation in mm/day were taken for 40 days. The results are shown in the following table.Temp.Evap.11.82.421.54.416.55.023.64.16.019.121.65.931.04.818.93.024.27.119.11.611.83.8 24.25.015.82.626.88.024.85.426.24.214.214.14.42.230.35.715.21.218.63.525.45.522.14.825.44.822.63.224.45.115.83.322.34.923.27.419.73.314.01.113.63.525.45.117.72.024.75.724.34.725.85.828.35.829.87.826.55.1Compute the least-squares line for predicting evaporation (y) from temperature (x).b.

How sensitive to changes in water temperature are coral reefs? To find out, scientists examined data on sea surface temperatures and coral growth per year at locations in the Gulf of Mexico and the Caribbean Sea. Scientists examined data on mean sea surface temperatures (in degrees Celsius) and mean coral growth (in centimeters per year) over a several‑year period at locations in the Gulf of Mexico and the Caribbean. The table shows the data for the Gulf of Mexico.

The age of a tree can be determined by counting each annual growth ring in the trunk of the tree. A common measure of the size of a tree is the "diameter at breast height" DBH. "Breast height" is defined as 4 ½ feet above the uphill side of the tree. Consider the following data on 12 northern red oaks from southwestern Wisconsin: 11 15 28 1.5 1.0 6.0 45 12 52 16.5 11.0 | 10.5 9.0 Age(years) | 97 93 88 81 75 57 1.0 DBH(inch) | 12.5 12.5 8.0 9.5 d) What is the range of validity of this model?

An ecologist hypothesizes a relationship between wing span of birds and the width of tree branches they use. The ecologist captured male birds, measured their wing span and other characteristics in millimeters, and then marked and released them. During the ensuing winter, the ecologist repeatedly observed the marked birds as they foraged for food on tree branches. He noted the branch diameter on each occasion, and calculated the average branch diameter for each bird in centimeters. The measurement data are below. What can the ecologist conclude with an a of 0.10? wing span branch diameter 79.3 80.1 80.7 81.5 79.5 80.7 81.1 80.5 80.7 1.02 1.04 1.21 1.15 1.21 1.56 1.39 1.31 1.39 a) What is the appropriate statistic?

Given the following histogram for a set of data, how many values in the data set are greater than 10.5 but less than 12.5? A histogram has a horizontal axis labeled Values from 7.5 to 16.5 in increments of 1 and a vertical axis labeled Frequency from 0 to 6 in increments of 1. The histogram has vertical bars of width 1, starting at the horizontal axis value of 7.5. The approximate heights of the bars are as follows, where the horizontal axis label is listed first and the approximate height is listed second: 7.5, 1; 8.5, 2; 9.5, 3; 10.5, 2; 11.5, 3; 12.5, 4; 13.5, 1; 14.5, 5; 15.5, 6.
