. A consumer organization is producing an article on refrigerators. The organization tests 20 m of refrigerator (under rigorous conditions), and determines how long each refrigerator ope properly before needing to be serviced. The histogram below shows the operation times (in mo until service is required. You may assume that in this data set there were no observations a class boundaries. Histogram of operation 2- 120 operation (a) What percentage of the refrigerators operate properly for more than 80 months? (b) Briefly describe the shape of this distribution. (c) Would a pie chart also be appropriate for describing these data? Explain briefly. Asuarbo

I need help with only question 14. I need help with parts a,b,c,d, and e.

Need help asap pls!

An investigation of the properties of bricks used to line aluminum smelter pots was published in an article. Six different commercial bricks were evaluated. The life span of a smelter pot depends on the porosity of the brick lining (the less porosity, the longer the life span); consequently, the researchers measured the apparent porosity of each brick specimen, as well as the mean pore diameter of each brick. See the table. Apparent Porosity (y). Mean Pore Diameter (x). Click the icon to view the table. Data table Mean Pore Diameter Apparent Porosity (%) (micrometers) Brick Interpret the y-intercept of the line. Choose the correct answer below. 18.7 12.0 В 18.3 9.8 O A. The y-intercept is Bo- This value has no meaning because 0 is not in the observed range of the independent variable mean pore diameter. 16.3 7.3 6.9 5.4 O B. The y-intercept is Bo: For each unit increase in mean pore diameter, the mean porosity is estimated to increase by B0- 17.2 10.9 O C. There is not enough…
