Section H: Hyla chrysoscelis is a type of gray tree frog with a distinct mating call. Frogs are cold-blooded animals, andtheir physiology is affected by variations in temperature. Researchers wanted to know if the mating song of Hylachrysoscelis is affected by the temperature of its natural habitat. They observed the mating song frequency (y innotes/sec) and the habitat (x in °Celsius) of 20 Hyla chrysoscelis in the wild. We aim to express the relationship betweenand y by using the simple linear regression model Yį = ßo + ß₁ x; + Eį.Table H.1CoefficientsStandardizedUnstandardized CoefficientsCoefficients95.0% Confidence Interval for BLower BoundBStd.

Question 5 Jade works at an insectarium and is conducting a study that investigates the possible effects of three different food types (type 1, 2 and 3) on adult size among three species of butterfly (species A, B and C). For each particular combination of food type and species, Jade randomly selected three butterflies from that species which were raised only on that food type until they reached adult size. For each butterfly, Jade recorded the adult wingspan (Y) in centimetres. Some sample statistics are displayed in the table below. Food Type Sum of Sample Values Sum of Squared Sample Values 1 Σ Υ = 38.7 Σ= Y = 168.93 2 Σ1Y2i = 44.1 3 ₁1Y3i = 52.2 A. Test whether the population variance of butterfly wingspan is the same for butterflies raised on food type 1 and for butterflies raised on food type 2. Clearly state your hypotheses and use a significance level of a = 5% Test whether the population mean wingspan of butterflies raised on food type 2 is greater than the population mean…
Question 4 Beachcomber Ltd in a local car dealership that sells used and new vehicles. The manager of the company wants to know how different variables affect the sales of his vehicles. A random sample of yearly data was taken with the view to testing the model: SALES=a+BAGE+YMIL+&ENG Where SÄLES= amount that a vehícle is sold for($000's), AGE = age of the vehicle, MIL= the total mileage of the vehicle at the point of sale and ENG= the size of the engine.
