Suppose a recent plant journal indicated that the mean height of mature plants of a certain species of sunflower is 10.1 ft. A biologist observing a huge field of mature plants of this particular species of sunflower thinks that the mean height is shorter than reported. He measures the heights of 35 randomly selected sunflowers and finds the mean height to be 9.6 ft. Select the correct null, H 0 , and alternative, H 1 , hypotheses.

Data from 2005 for various age groups show that for each $100 increase in the median weekly income for whites, the median weekly income of blacks increases by $105. also, for workers of ages 25 to 54 the median weekly income for whites was $676 and for blacks was $527. (a) let w represent the median weekly income for whites and b the median weekly income for blacks, and write the equation of the line that gives b as a linear function of w. b = (b) when the median weekly income for whites is $760, what does the equation in (a) predict for the median weekly income for blacks?
