(a) at the 5% significance level, the data provide convincing evidence of a real difference in the proportion who are not affected personally between americans who make less than $40,000 annually and americans who make $40,000 annually. (b) we are 95% confident that 16% more to 2% fewer americans who make less than $40,000 per year are not at all personally affected by the government shutdown compared to those who make $40,000 or more per year. (c) a 90% confidence interval for (p< 40k − p≥40k) would be wider than the (−0.16, 0.02) interval. (d) a 95% confidence interval for (p≥40k − p< 40k) is (-0.02, 0.16).

Which triangles area would be calculated using the trigonometric area formula

The data shown in the table below represents the weight, in pounds, of a little girl, recorded each year on her birthday. age (in years) weight (in pounds) 2 32 6 47 7 51 4 40 5 43 3 38 8 60 1 23 part a: create a scatter plot to represent the data shown above. sketch the line of best fit. label at least three specific points on the graph that the line passes through. also include the correct labels on the x-axis and y-axis. part b: algebraically write the equation of the best fit line in slope-intercept form. include all of your calculations in your final answer. part c: use the equation for the line of best fit to approximate the weight of the little girl at an age of 14 years old.

Which of the following equations is of the parabola whose vertex is at (2, 3), axis of symmetry parallel to the y-axis and p = 4? a.)y-3 = 1/16 (x-2)^2 b.)y+3 = -1/16 (x+2)^2 c.)x-2 = 1/16 (y-3)^2
