Math Problem Statement

Develop a 95% confidence interval for the mean amount of total itemized deductions and a 95% prediction interval for a specific taxpayer with an adjusted gross income of $52,500, using the regression equation Ŷ = 4.68 + 0.16X. Analyze whether IRS auditing guidelines justify further review for a taxpayer claiming $20,400 in deductions.

Problem Overview:

  • The estimated regression equation is Y^=4.68+0.162X\hat{Y} = 4.68 + 0.162X, where:

    • Y^\hat{Y} is the estimated total itemized deductions (in thousands of dollars).
    • XX is the adjusted gross income (in thousands of dollars).
  • The data given for adjusted gross income and corresponding itemized deductions (in thousands of dollars) is as follows:

    • 22 (Adjusted Gross Income) → 9.6 (Deductions)
    • 27 → 9.6
    • 32 → 10.1
    • 48 → ?
    • 65 → ?
    • 85 → 17.7
    • 120 → 25.5
  • The task is to:

    1. Develop a 95% confidence interval for the mean amount of total itemized deductions for taxpayers with an adjusted gross income of $52,500.
    2. Develop a 95% prediction interval for a particular taxpayer with an adjusted gross income of $52,500.
    3. Determine if the IRS agent's request for an audit is justified if a taxpayer claims itemized deductions of $20,400.
    4. Provide a guideline for the IRS agent on the amount of deductions a taxpayer should claim before triggering an audit.

I'll proceed to solve parts (a) and (b) first by calculating the confidence and prediction intervals.

Would you like me to start solving the problem, or would you prefer to focus on a specific part first?
