Question 2 (1 point) Which of the following statements are true regarding the evolution of seed plants? Gymnosperms have naked seeds and include pine trees. By the early (Triassic, c. 240 MYA) and middle (Jurassic, c. 205 MYA) Mesozoic era, the landscape was dominated by gymnosperms. Angiosperms surpassed gymnosperms by the middle of the Cretaceous (c. 100 MYA) in the late Mesozoic era, and today are the most abundant and biologically diverse plant group in most terrestrial biomes. Angiosperms are flowering plants.

By the early (Triassic, c. 240 MYA) and middle (Jurassic, c. 205 MYA) Mesozoic era, the landscape was dominated by angiosperms. Both pollen and seeds expanded the colonization of land by plants. Fossils place the earliest distinct seed plants at about 350 mya.

S. DETAILS The following data show the brand, price (5), and the overall score for six stereo headphones that were tested by a certain magazine. The overall score is based on sound quality and effectiveness of ambient noise reduction. Scores range from 0 (lowest) to 100 (highest). The estimated regression equation for these data is $\hat{y} = 19.849498 + 0.351505x$, where $x = \text{price (\$)}$ and $y = \text{overall score}$. Brand Price (\$) Score A 180 78 B 150 73 C 95 63 D 70 54 E 70 38 F 35 24 (a) Compute SST, SSR, and SSE. (Round your answers to three decimal places.) SST = SSR = SSE = (b) Compute the coefficient of determination, $r^2$. (Round your answer to three decimal places.) $r^2 = $ Comment on the goodness of fit. (For purposes of this exercise, consider a proportion large if it is at least 0.55.) The least squares line provided a good fit as a small proportion of the variability in y has been explained by the least squares line. The least squares line did not provide a good fit as a large proportion of the variability in y has been explained by the least squares line. The least squares line did not provide a good fit as a small proportion of the variability in y has been explained by the least squares line.
