Consider this population data set: 4.6, 7, 11, 12, 18, 26, 23, 14, 31, 22, and 12. The values 11. 31, 22, and 12 constitute a random sample drawn
from the data set.
The sample mean is more than the population mean by

Amodel rocket is launched from a roof into a large field. the path of the rocket can be modeled by the equation y = -0.04x^2 + 8.6x + 4.8, where x is the horizontal distance, in meters, from the starting point on the roof and y is the height, in meters, of the rocket above the ground. how far horizontally from its starting point will the rocket land? a. 0.56 m b. 215.56 m c. 431.11 m d. 215.74 m
