Transcript text: 7 If the test point chosen makes the inequality statement true, then one should be sure to shade the area that contains the test point. Select one: True False

Solution

Solution Steps

The question is asking whether shading the area that contains a test point, which makes an inequality true, is the correct approach. In the context of graphing inequalities, if a test point satisfies the inequality, the region containing that point is the solution region and should be shaded.

Solution Approach

Determine if the statement is true or false based on the explanation above.

Step 1: Understanding the Context of the Question

The question is about graphing inequalities and determining whether the statement regarding shading the area containing a test point is true or false. When graphing inequalities, a test point is used to determine which side of the boundary line should be shaded. If the test point satisfies the inequality, the region containing that point is the solution region.

Step 2: Analyzing the Statement

The statement given is: "If the test point chosen makes the inequality statement true, then one should be sure to shade the area that contains the test point." This statement is consistent with the standard procedure for graphing inequalities. If a test point satisfies the inequality, it indicates that the region containing the test point is part of the solution set.

Final Answer

True

A study examined whether the content of TV shows influenced the ability of viewers to recall brand names of items featured in the commercials. Analysts recorded the number of advertised brand names a group of people recalled immediately after watching TV shows and then that same group of people recalled 24 hours later. Strangely enough, it appears that they remembered more about the ads the next day. Should we conclude this is true in general about people's memory of TV ads? Complete parts a through d. c) How might the design of this experiment have tainted these results? A. Since the populations of each group are not normally distributed, subjects with high recall could skew the means for each group. B. Since the populations of each group are not normally distributed, a two-sample t-test is not appropriate to compare the means between the two groups. C. Since the subjects were not selected at random, the first interview might have helped the subjects with high recall to remember the brand names for a longer period of time than they would have otherwise. D. A subject with high recall right after the show might have high recall 24 hours later as well. Also, the first interview might have helped the subjects to remember the brand names for a longer period of time than they would have otherwise. d) Suggest a design that could compare immediate brand name recall with recall one day later. A. Randomly assign half of the group watching violent TV shows to be interviewed immediately after watching, while the other half of the group is interviewed 24 hours later. B. Assign the older half of the group watching violent TV shows to be interviewed immediately after watching, while the younger half of the group is interviewed 24 hours later. C. Assign subjects in the group with horrible short-term memory to be interviewed immediately after watching the violent TV show, and assign subjects with horrible long-term memory to be interviewed 24 hours later. D. Assign subjects in the group with good short-term memory to be interviewed immediately after watching the violent TV show, and assign subjects with good long-term memory to be interviewed 24 hours later.
