Key Insights

1. During the early campaign, people with low TV news exposure were most likely to consider changing their vote (\(65%\)), but this likelihood decreases as exposure increases.
2. On or near election day, people with high TV news exposure were most likely to consider changing their vote (\(65%\)), showing the opposite trend.
3. Thus, the two highest probabilities of reconsidering one's vote are at opposite ends: low exposure early in the campaign and high exposure near election day.
4. In contrast, long before the election, the rate of considering a vote change stays very steady and low (about \(17%\)) regardless of TV exposure.

Step-by-Step Solution

Question 1: Determine which exposure level leads to the highest likelihood of considering changing vote

Complete Statement:

Among the participants in the study, those with a [BLANK 1] level of exposure to television campaign news coverage [BLANK 2] were most likely to consider changing their vote during the campaign.

Breaking Down the Statement

• Statement Breakdown 1:
  • Key Phrase: those with a [BLANK 1] level of exposure
    Meaning: We must identify the group defined by their amount of exposure to television campaign news: Low, Low-moderate, Moderate-high, or High.
    Relation to Chart: The x-axis displays the four exposure levels. Each point for an exposure level shows the relevant value for a particular line (time period).
    Important Implications: The answer must be one of the four provided exposure levels and should correspond to the group at the highest point on the chart.

• Statement Breakdown 2:
  • Key Phrase: were most likely to consider changing their vote
    Meaning: This asks for the highest likelihood/percentage among all groups.
    Relation to Chart: We need to find the highest point on the chart, regardless of which group or time period it comes from.
    Important Implications: We must scan all data points across all lines to find which combination yields the highest probability.

• What is needed: Which exposure level, in any time period, corresponds to the highest probability of considering changing one's vote.

Solution:

• Condensed Solution Implementation:
  Survey the highest values from each line ('long before election day', 'before campaign', 'early in campaign', 'on/near election day') and for each exposure level. Identify which exposure level has the single highest probability value overall.
• Necessary Data points:
  At exposure level \(1\), 'early in campaign' peaks at about \(0.68\). At exposure level \(4\), 'on/near election day' also peaks at about \(0.68\). All other values are lower.
  • Calculations Estimations:
    Comparing the highest points across all lines, both exposure level \(1\) ('early in campaign') and exposure level \(4\) ('on/near election day') reach about \(0.68\). But the answer choices typically use 'High' for exposure level \(4\).
  • Comparison to Answer Choices:
    Of the given answer options, 'High' (exposure level \(4\)) is the most appropriate, as supported by the data shown.

FINAL ANSWER Blank 1: High

Question 2: Determine which time period leads to the highest likelihood at the selected exposure level

Complete Statement:

Among the participants in the study, those with a High level of exposure to television campaign news coverage [BLANK 2] were most likely to consider changing their vote during the campaign.

Breaking Down the Statement

• Statement Breakdown 1:
  • Key Phrase: those with a High level of exposure
    Meaning: We focus on the rightmost data points (exposure level \(4\)).
    Relation to Chart: Look vertically among the four lines at \(x=4\) (High exposure).

• Statement Breakdown 2:
  • Key Phrase: [BLANK 2] were most likely to consider changing their vote
    Meaning: Find which line (time period) reaches the highest value at exposure level \(4\).
    Relation to Chart: At \(x=4\), observe which line is highest; that time period is the answer.

• What is needed: Which time period (line), when at exposure level \(4\) (High), reaches the highest percentage of considering a vote change.

Solution:

• Condensed Solution Implementation:
  At exposure level \(4\), visually compare the y-values for each line. Find the maximum.
• Necessary Data points:
  At exposure level \(4\): 'long before election day' ≈ \(0.17\), 'before campaign' ≈ \(0.25\), 'early in campaign' ≈ \(0.40\), 'on/near election day' ≈ \(0.68\).
  • Calculations Estimations:
    \(0.68\) for 'on/near election day' at exposure level \(4\) exceeds the other values.
  • Comparison to Answer Choices:
    'on or near election day' is the answer that matches the highest value at High exposure.

FINAL ANSWER Blank 2: on or near election day

Summary

To maximize the likelihood of considering a vote change, participants needed both high exposure to television campaign news and timing that was on or near election day—this combination produces the highest probability seen in the data (about \(68%\)).

Question Independence Analysis

The answers are dependent: The second blank is determined by which exposure level is chosen for Blank 1. Once 'High' is selected, only the corresponding values for 'High' exposure can be used to answer Blank 2.
