Consider the following data on the estimated cost (in millions of dollars) resulting from traffic congestion for different urban
IrinaK [193]

The mean is $5.769 million and the standard deviation is $3.905 million.

<h3>What is the mean?</h3>

The mean is the average of a data set.

<h3>What is the standard deviation?</h3>

The standard deviation shows the measure of the dispersion from the mean.

<h3>Data and Calculations:</h3>

Urban Area         Total Cost       Squared Difference

                        (millions of dollars)    (x - u)²

New York                  16                     104.65  

Los Angeles              13                      52.27

Chicago                      7                          1.51

Washington, D.C.       5                        0.59

Houston                      5                        0.59

Dallas, Fort Worth      4                         3.13

Detroit                        4                          3.13

Miami                         4                          3.13

Phoenix                     4                          3.13

Philadelphia              4                          3.13

San Francisco           3                          7.67

Boston                       3                          7.67

Atlanta                       3                          7.67

13    Total                 75                       198.27

Mean = 5.769 (75/13)                         15.251 (198.27/13)

Standard Deviation = 3.905 (square root of 15.251)

Calculate the mean and standard deviation for this data set (in millions of dollars). (Round your answers to three decimal places.) mean $ million standard deviation $ million

Thus, the mean is $5.769 million and the standard deviation is $3.905 million.

The pattern of numbers below is an arithmetic sequence:
vivado [14]

Answer:

The common difference is 4, so the function is f(n + 1) = f(n) + 4 where f(1) = 10.

Step-by-step explanation:

14 + 10 = 24

24 + 10 = 34

34 + 10 = 44

44 + 10 = 54

54 + 10 = 64
