70 college students were asked what their favorite year of high school was. The data collected was compiled into this frequency chart. Interpret the meaning of the number 17 on the chart.

17 respondents said their favorite year was their sophomore year.

The students asked replied they were 17 during their favorite year.

17 sophomores were asked what their favorite year was.

The average sophomore is 17 years old.

Is 28 an outlier in the following data set? 8, 9.5, 13.5, 14, 14, 16, 28

Yes, because anything greater than 25.75 is an outlier

Yes, because anything greater than 22.5 is an outlier

No, because it must be greater than 34.5 to be an outlier

Yes, because anything greater than 19.25 is an outlier

Calculate the mean of the following distribution: 5.5, 10.5, 12, 11.5, 19, 19.5, 20 Would the mean change if the data value 20 (the maximum) was replaced with 30?

Mean: 14 ; Yes because the mean is not resistant to extreme values.

Mean: 11.5 ; Yes because the mean is not resistant to extreme values.

Mean: 11.5 ; No because the mean is resistant to extreme values.

Mean: 14 ; No because the mean is resistant to extreme values.

Describe this scatterplot.

Negative, non-linear, strong association with no outliers

Positive, linear, weak association with no outliers

Positive, non-linear, moderate association with an outlier at (250,450)

Negative, linear, weak association with an outlier at (50,1950)

Is this a valid statistical question? How many text messages does the average high school student send each day?

Yes, it is a valid statistical question.

No, it is not a valid statistical question.

A teenager randomly selects 5 episodes of The Walking Dead to binge watch. Identify the population and sample.

Researchers want to test if a new medicine will help people who have trouble falling asleep. To determine if the medicine works, they give it to 100 volunteers who report having trouble sleeping. After using the medicine for one week, the volunteers will report back on how the medication worked. Why should a control group be used in this study?

It will be used as a point of comparison for any findings from the group who received the treatment.

It increases confounding, showing researchers possible future studies to look into.

It will reduced the likelihood of response bias, as volunteers are more likely to lie about their sleeping patterns.

It will result in the placebo effect and even more people will sleep better.

What is the problem with voluntary response sampling?

Those who volunteer are likely to feel strongly about the question and are not always representative of the population.

Volunteers do not try to be accurate compared to selected participants.

Data from volunteers will be more variable than data from selected participants.

Volunteers are more likely to cause the study to suffer from response bias.

A biology class conducted an experiment to investigate the impact of different light regimens on the growth of radish plants. They assigned 20 plants to artificial "grow-light" lamps and 20 plants to natural sunlight. In terms of experimental design, does it matter if each plant is exposed to the light for different lengths of time?

It matters because if the length of time each plant receives light is different, the response variable will show much more variability and there is potential for confounding.

It doesn't matter, since the findings will only be statistically significant if there is a large enough difference in the growth of each plant.

It doesn't matter because the number of plants was kept the same and random assignment was used.

It matters because radishes are very sensitive to too much light.

Which statement is true about the characteristics of the three lines in the graph?

They have the same x-intercept.

They have the same y-intercept.

What is the solution set of ∣ 3 x − 2 ∣ = 7 ? \left|3x-2\right|=7\ ? ∣ 3 x − 2 ∣ = 7 ?

− 5 3 , 3 -\frac{5}{3},3 − 3 5 , 3
