Please correct my answers for b and c with explanation. Need to understand for exam, thanks! A magazine devoted to cycling, reviews hundreds of bicycles throughout the year. Its Road-Race category contains reviews of bicycles used by riders primarilyinterested in racing. One of the most important factors in selecting a bicycle for racing is its weight. The following data show the weight (pounds) and price($) for 10 racing bicycles reviewed by the magazine.ModelWeight (Ib)Price ($)Model 117.82,100Model 216.26,250Model 314.98,570Model 416.06,400Model 517.24,200Model 613.28,800Model 716.26,200Model 817.22,780Model 917.63,400Model 1014.28,000(a) Develop a scatter chart with weight as the independent variable. What does the scatter chart indicate about the relationship between the weight andprice of these bicycles?O The scatter chart indicates there may be no noticeable linear relationship between weight and price.O The scatter chart indicates there may be a positive linear relationship between weight and price.O The scatter chart indicates there may be a negative linear relationship between weight and price. (a) Develop a scatter chart with weight as the independent variable. What does the scatter chart indicate about the relationship between the weight andprice of these bicycles?O The scatter chart indicates there may be no noticeable linear relationship between weight and price.O The scatter chart indicates there may be a positive linear relationship between weight and price.O The scatter chart indicates there may be a negative linear relationship between weight and price.(b) Use the data to develop an estimated regression equation that could be used to estimate the price in dollars (y) for a bicycle, given its weight (x) inpounds. What is the estimnated regression model? (Round your numerical values to two decimal places.)= 29500 –1484.7x(c) Test whether the regression parameter fo is equal to zero at a 0.05 level of significance.Find the p-value. (Round your answer to four decimal places.)p-value = 7.9399

We should find the regression equation. Please find the solution below. Thank you.

In 2010, the U.S. Congress passed the historic health care reform bill that will provide some type of coverage for the 32 million Americans currently without health care insurance. Just how widespread is the lack of medical coverage? The media claim that the segments of the population most at risk for disease and thus needing healthcare are women, children, the elderly and the poor. The following tables were generated from the U.S. Census Bureau, Current Population Survey, Annual Social and Economic Supplement (2011). The tables report the number of uninsured (in thousands) by sex, by age, and by household income. Is being insured or not dependent on gender? Fill in the degrees of freedom and p-value in the output below and draw a clear conclusion indicating which gender is more at risk of not being insured if there is a significant difference.
