The article "Snow Cover and Temperature Relationships in North America and Eurasia"t used statistical techniques to relate the amount of snow cover on each continent toaverage continental temperature. Data presented there included the following ten observations on October snow cover for Eurasia during the years 1970-1979 (in million km2):6.5 12.014.910.010.77.921.912.514.59.2What would you report as a representative, or typical, value of October snow cover for this period, and what prompted your choice?O The mean of this sample because the mean is always the best central measure.The mean of this sample because a potential outlier may produce a misleading median.The median of this sample because a potential outlier may produce a misleading mean.The median of this sample because the median is always the best central measure.

The Given data has been arranged in increasing order 6.5 7.9 9.2 10 10.7 12…

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…
