The number of calls received by a technical support center during 22 randomly selected days is listed. Identify the outlier, and describe how it affects the mean and the standard deviation. 50, 57, 77, 66, 50, 57, 77, 66, 53, 72, 51, 88, 82, 70, 62, 64, 69, 88, 98, 65, 11, 68

The outlier is 11. The outlier in the data set causes the mean to decrease from about 68.1 to 65.5 and the standard deviation to increase from about 13.33 to about 17.81.

The outlier is 11. The outlier in the data set causes the mean to decrease from about 17.81 to about 13.33 and the standard deviation to increase from 65.5 to about 68.1.

The outlier is 88. The outlier in the data set causes the mean to decrease from about 17.81 to about 13.33 and the standard deviation to increase from 65.5 to about 68.1.

The outlier is 88. The outlier in the data set causes the mean to increase from 65.5 to about 68.1 and the standard deviation to decrease from about 17.81 to about 13.33.

The data set below shows 15 students' scores on a test. Describe the shape of the data distribution if the student who scored 100 is not included in the data set. 70, 72, 73, 74, 74, 75, 75, 75, 75, 76, 77, 77, 78, 80, 100

The data distribution is symmetric.

The data distribution is skewed right.

The data distribution is skewed left.

It is impossible to determine the shape of the data distribution.

For which situation would you expect to see no correlation?

The height of a person and the number of books they read last year.

Vjay's family is staying at a campground this summer. The table shows the canoe rental rates at this campground. Write a linear equation to model the relationship between the total cost, c , and the rental time, h , for canoe rentals. Then give real-world interpretations for the slope and y-intercept in your equation.

c = 0.60 h + 3.24 c=0.60h+3.24 c = 0 . 6 0 h + 3 . 2 4 The slope, 0.60, represents the hourly cost of the rental. The y-intercept, 3.24, represents the one-time fee for the rental.

c = 2.22 h c=2.22h c = 2 . 2 2 h The slope, 2.22, represents the hourly cost of the rental. The y-intercept is 0, so there is no one-time fee for the rental.

c = 1.01 h c=1.01h c = 1 . 0 1 h The slope, 1.01, represents the hourly cost of the rental. The y-intercept is 0, so there is no one-time fee for the rental.

c = 1.67 h + 5.40 c=1.67h+5.40 c = 1 . 6 7 h + 5 . 4 0 The slope, 5.40, represents the hourly cost of the rental. The y-intercept, 1.67, represents the one-time fee for the rental.

You find a line of fit for a set of data and calculate that the correlation coefficient for the model is -0.34. Which statement best describes the fit of the model to the data?

The correlation coefficient suggests a weak negative correlation, so this model is not a good fit for the data.

The correlation coefficient suggests a strong positive correlation, so this model is a good fit for the data.

The correlation coefficient suggest a weak positive correlation, so this model is not a good fit for the data.

The correlation coefficient suggests a strong negative correlation, so this model is a good fit for the data.

The table shows the sizes and prices of some homes listed for sale in San Jose, California in 2010. The equation for the least squares lines for the data is y ≈ 0.367 x + 0.163 y\approx0.367x+0.163 y ≈ 0 . 3 6 7 x + 0 . 1 6 3 and r ≈ 0.96 r\approx0.96 r ≈ 0 . 9 6 . Discuss correlation and causation for the data set.

There is a strong positive correlation between a home's size and its price. There is a likely cause-and-effect relationship because it is likely that people will pay more money for a larger home.

There is a weak positive correlation between a home's size and its price. There is a likely cause-and-effect relationship because it is likely that people will pay more money for a larger home.

There is a strong positive correlation between a home's size and its price. There is not a likely cause-and-effect relationship because other factors, such as the number of bedrooms, also affect a home's price.

There is a weak positive correlation between a home's size and its price. There is not a likely cause-and-effect relationship because other factors, such as the number of bedrooms, also affect a home's price.

Which equation could be used to approximate the data in the scatter plot below?

y = 1 2 x y=\frac{1}{2}x y = 2 1 x

y = ( 1 2 ) x y=\left(\frac{1}{2}\right)^x y = ( 2 1 ) x

Which exponential function is a good fit for the data in the table below?

y = 135.17 ( 1.29 ) x y=135.17\left(1.29\right)^x y = 1 3 5 . 1 7 ( 1 . 2 9 ) x

y = − 135.17 ( 1.29 ) x y=-135.17\left(1.29\right)^x y = − 1 3 5 . 1 7 ( 1 . 2 9 ) x

y = − 120.47 ( 150.07 ) x y=-120.47\left(150.07\right)^x y = − 1 2 0 . 4 7 ( 1 5 0 . 0 7 ) x

y = 120.47 ( 150.07 ) x y=120.47\left(150.07\right)^x y = 1 2 0 . 4 7 ( 1 5 0 . 0 7 ) x

Which linear function is a good fit for the data in the table below?

y = 4.9 x + 2 y=4.9x+2 y = 4 . 9 x + 2

y = 4.9 x − 2 y=4.9x-2 y = 4 . 9 x − 2

y = − 4.9 x + 2 y=-4.9x+2 y = − 4 . 9 x + 2

y = − 4.9 x − 2 y=-4.9x-2 y = − 4 . 9 x − 2

Anya is studying a textbook. Each day, she works through a few pages of the book. She tracks how long it is taking her to work through the textbook, and finds that the equation y = 14x +2 approximates the total pages studied after any number of days. Which statement is true based on this equation?

Anya studies approximately 14 pages each day.

Anya studies approximately 2 pages each day.

Anya studies approximately 7 pages each day.

Anya studies approximately 12 pages each day.
