A group of scientists are comparing the adult weight of meerkats bred in captivity to those living wild in the Kalahari Desert.  What type of numerical data are the scientists recording?

A famous data set gives measurements of 143 fish of 6 species caught from the same lake (Längelmävesi) in Finland. The data can be used to model the relationship between weight and length (from the nose to the end of the tail). Weight is measured in grams and length is measured in cm. As might be expected, the relationship between weight and length is nonlinear and so logarithms (to base 10) were taken of both variables prior to analysis.Of interest was a comparison between two of the species, Saerki and Parkki. A multiple linear regression analysis of the log-transformed data in R gave the following (edited) output:Coefficients: Estimate Sd. Error (Intercept) -2.1424 0.1525log10(Length3) 3.0794 0.1092SpeciesParkki 0.1148 0.0169Based on this model, the estimated weight for a 40 cm Parkki is   g

Which piece of equipment can be used to estimate the population size of a given species in a defined area?CalculatorTransectQuadratTape measure2A student measures the number of snails in a garden by taking 10 random 1 m2 quadrat readings. If the numbers recorded are 3, 2, 1, 4, 2, 4, 5, 5, 2 and 2, what is the mean number of snails per m2 in the garden?302343A field measures 10 m by 30 m. In ten 1 m2 quadrats thrown randomly onto the field, an average of 5 flowers is counted. What is the estimated number of flowers on the whole field? 150050030001504What is a quadrat placed along a transect used to measure? The sizes of different species in a defined areaA change in species distribution along a set lineThe numbers of different species along a set lineThe estimated population of a single species in a defined area5Which of the following are abiotic factors that might affect the distribution of a species?TemperatureImmersion by waterAll of theseLight intensity

When an anthropologist finds skeletal remains, they need to figure out the height of the person. The height of a person (in cm) and the length of their metacarpal bone (in cm) were collected for 28 sets of skeletal remains. The data are in the table below.X, caloric content Y, sodium content187 499190 645111 300140 326141 386139 322177 429135 298184 482190 587176 483186 495159 374148 375132 253157 440152 330181 477131 317182 481149 319153 401149 322158 370150 326175 479176 425191 591a) State the random variables.    rv X = of     rv Y = of b) The symbol and value of the correlation coefficient are as follows:    Round final answer to 3 decimal places.
