An old study done in the 1920s considered the relationship between a farm's corn yield and bushels per acre and the land value per acre of that farm. The study found that the data had a less squares regression equation of y = 12.32x - 273.6
— Interpret the slope of the least square regression line.

Alpha: For every additional dollar of land value, the corn yield tends to decrease by 273.6 bushels per year.

Bravo: For every additional bushel per year of corn a farm produces, the land value tends to decrease by $273.60 per acre.

Charlie: For every additional dollar of land value, the corn yield tends to increase by 12.32 bushels per year.

Delta: Forevery additional bushel per year of corn a farm produces the land value tends to increase by $12.32 per acre.​

Apoll is being conducted at a mall nothingto obtain a sample of the population of an entire country. what is the frame for this type of​ sampling? who would be excluded from the survey and how might this affect the results of the​ survey? what is the frame for this type of​ sampling? a. the frame is people who need new clothes. b. the frame is people who shop at the mall. c. the frame is people who like to shop. d. the frame is the entire population of the country. who would be excluded from the survey and how might this affect the results of the​ survey? a. any person that does not need new clothes is excluded. this could result in sampling bias due to undercoverage. b. any person who does not shop at the mall is excluded. this could result in sampling bias due to undercoverage. c. any person who does not shop at the mall is excluded. this could result in nonresponse bias due to people not participating in the poll. d. there is nobody that is being excluded from the survey.
