Solution Steps

Step 1: Determine Electron Geometry for Part A
  • A molecule with 4 outer atoms and 1 lone pair on the central atom has a total of 5 regions of electron density.
  • The electron geometry for 5 regions of electron density is trigonal bipyramidal.
Step 2: Determine Molecular Geometry for Part A
  • With 1 lone pair, the molecular geometry is "seesaw."
Step 3: Determine Electron Geometry for Part B
  • A molecule with 4 outer atoms and 2 lone pairs on the central atom also has 5 regions of electron density.
  • The electron geometry remains trigonal bipyramidal.
Step 4: Determine Molecular Geometry for Part B
  • With 2 lone pairs, the molecular geometry is "T-shaped."
Step 5: Determine Electron Geometry for Part C
  • A molecule with 2 outer atoms and 3 lone pairs on the central atom has 5 regions of electron density.
  • The electron geometry is still trigonal bipyramidal.
Step 6: Determine Molecular Geometry for Part C
  • With 3 lone pairs, the molecular geometry is "linear."

Final Answer

Part A: \(\boxed{\text{seesaw}}\)
Part B: \(\boxed{\text{T-shaped}}\)
Part C: \(\boxed{\text{linear}}\)

Assume that in a political science class, the teacher gives a midterm exam and a final exam. Assume that the association between midterm and final scores is linear. The summary statistics shown below have been simplified for clarity. Also, r=0.7 and n=26. Mean Standard deviation ------------------------------------ Midterm 75 10 Final 75 10 According to the regression equation, for a student who gets an 87 on the midterm, what is the predicted final exam grade? What phenomenon does this demonstrate? Explain. The predicted final exam grade is 83 (Round to the nearest integer as needed.) Step 3: Your predicted final exam grade should be less than 87. Why? What phenomenon does this demonstrate? Explain. Choose the correct answer below. A. Regression toward the mean, because the student's predicted score is closer to the mean than was their midterm score. B. Regression toward the mean, because the student's predicted final score is farther from the mean than was their midterm score. C. Extrapolation, because the predicted score is lower than the midterm score. D. Extrapolation, because the score of 87 is outside the range of the data.
