 The data attached contains information on customers\u2019 ratings of your product (CustRate), on a scale of 1 to 100, along with demographic information. The demographic information includes: income (Inc), age (Age), education (Educ), and marital status (Marr). The last variable equals one if the respondent is married and zero otherwise. Assume the data-generating process can be written as:<\/p>\n

CustRatei<\/em>=\u03b1+\u03b21Inci<\/em>+\u03b22Agei<\/em>+\u03b23Educi<\/em>+\u03b24Marri<\/em>+Ui<\/em>.<\/p>\n

  1. Test the hypothesis that income has no impact on customer rating, using a confidence level of 95%. Be sure to provide the reasoning behind your result.<\/li>\n
  2. Test the hypothesis that \u03b22=0.05, using a confidence level of 90%. Be sure to provide the reasoning behind your result.<\/li>\n
  3. Build a 95% confidence interval for the impact of education on customer rating. Be sure to provide the reasoning for your result.<\/li>\n
  4. Build a 95% confidence interval for the impact of being married on customer rating. Be sure to provide the reasoning for your result.<\/li>\n
  5. Predict the change in customer rating if a customer\u2019s income increases by $10,000, with no change in age, education, or marital status.<\/li>\n<\/ol>\n","protected":false},"excerpt":{"rendered":"
