(a)
Answer to Problem 9E
Explanation of Solution
Given:
The given data is:
Calculation:
From the given data;
Draw the histogram of the given data as follows:
(b)
The measures of center and variation that best describe the data.
(b)
Answer to Problem 9E
Use the median to describe the center and five-number summary to describe the variation.
Explanation of Solution
Given:
The given data is:
Calculation:
The histogram of the given data as follows:
The tail of the graph extends to the right. Most of the data is on the left. Hence, the distribution is skewed right.
Therefore, use the median to describe the center and five-number summary to describe the variation.
(c)
The interpretation of the data.
(c)
Answer to Problem 9E
Most people withdraw less than $150 and hence, were charged a bank fee.
Explanation of Solution
Given:
The given data is:
Bank charges a fee for any ATM withdrawal less than $150.
Calculation:
Looking at the data and the histogram, it can be seen that most people withdraw less than $150 and hence, were charged a bank fee.

- The answer is B, Could you please show the steps to obtain the answerarrow_forward2. Suppose that U(x, y, z) = x² + y²+ z² represents the temperature of a 3-dimensional solid object at any point (x, y, z). Then F(x, y, z) = -KVU (x, y, z) represents the heat flow at (x, y, z) where K > 0 is called the conductivity constant and the negative sign indicates that the heat moves from higher temperature region into lower temperature region. Answer the following questions. (A) [90%] Compute the inward heat flux (i.e., the inward flux of F) across the surface z = 1 - x² - y². (B) [10%] Use the differential operator(s) to determine if the heat flow is rotational or irrotational.arrow_forwardCould you show why the answer is B Using polar coordinates and the area formulaarrow_forward
- 1. The parametric equations x = u, y = u cos v, z = usin v, with Ou≤ 2, 0 ≤ v ≤ 2π represent the cone that is obtained by revolving (about x-axis) the line y = x (for 0 ≤ x ≤2) in the xy-plane. Answer the following questions. (A) [50%] Sketch the cone and compute its surface area, which is given by dS = [ | Ər Or ди მა × du dv with S being the cone surface and D being the projection of S on the uv-plane. (B) [50%] Suppose that the density of the thin cone is σ(x, y, z) = 0.25x gr/cm². Compute the total mass of the cone.arrow_forwardThe value of sin (2V · F) at x = 3, y = 3, z = −4, where F -0.592 -0.724 0.661 -0.113 -0.822 -0.313 0.171 0.427 = (-2x² + -4,2yz − x − 3, −5xz - 2yz), isarrow_forward14 A survey is conducted to determine whether would prefer to work at home, if given the 20 office employees of a certain company chance. The overall results are shown in the first bar graph, and the results broken down by gender are presented in the second. a. Interpret the results of each graph. b. Discuss the added value in including gen- der in the second bar graph. (The second bar graph in this problem is called a side by side bar graph and is often used to show results broken down by two or more variables.) c. Compare the side by side bar graph with the two pie charts that you made for Question 6. Which of the two methods is best for comparing two groups, in your opinion?
