The traffic engineer for a large city is conducting a study on traffic flow at a certain intersection near the city administration building. The engineer will collect data on different variables related to the intersection each day for ten days. Of the following variables, which will be measured using continuous data?
E?
The number of cars passing through the intersection in one hour
A
The number of pedestrians crossing the intersection in one hour
B
The number of bicyclists crossing the intersection in one hour
C
The number of food trucks that park within four blocks of the intersection
D
The number of minutes for a car to get from the intersection to the administration building E
The following dotplot shows the number of strokes taken by 20 professional golfers competing at an 18-hole golf course.
The figure presents a dotplot titled Number of Strokes, and the numbers 62 through 70 are indicated, in increments of 1. The dotplot contains 20 data points. The data are as follows. 62 strokes, 0 golfers. 63 strokes, 0 golfers. 64 strokes, 2 golfers. 65 strokes, 4 golfers. 66 strokes, 2 golfers. 67 strokes, 6 golfers. 68 strokes, 3 golfers. 69 strokes, 3 golfers. 70 strokes, 0 golfers.
Which of the following best describes the type of variable represented in the dotplot?
A??
Quantitative and discrete
A
Quantitative and continuous
B
Categorical and discrete
C
Categorical and continuous
D
Quantitative and categorical
E
The figure presents a histogram. The horizontal axis is labeled Tree Diameter, in centimeters, and the numbers 0 through 55, in increments of 5, are indicated. The vertical axis is labeled Frequency, and the numbers 0 through 30, in increments of 5, are indicated. The data represented in the histogram are as follows. Note that all values are approximate. 0 through 5 centimeters, 4. 5 through 10 centimeters, 20. 10 through 15 centimeters, 27. 15 through 20 centimeters, 22. 20 through 25 centimeters, 6. 25 through 30 centimeters, 0. 30 through 35 centimeters, 0. 35 through 40 centimeters, 0. 40 through 45 centimeters, 4. 45 through 50 centimeters, 10. 50 through 55 centimeters, 6.
Which of the following is the best description of the distribution?
A? there is two clusters on each side with a gap between 25-40, but would that be the best terminology or would it be a right skew?
The distribution consists of two clusters and a gap.
A
The distribution is approximately normal.
B
The distribution is symmetric with a skew to the right.
C
The distribution is skewed to the left.
D
The distribution is uniform.
E
PsyDAG I don't know what you're mad about but she clearly gave her opinion and her thoughts of why she chose it. Since you don't know the answer just don't respond or admit it. Thanks!
I put the choices above right below the question 1. E 2. A 3. A
what do you mean: M.E.T.H or meth
im on a roll just like a lobster
For the first question, the variable that will be measured using continuous data is the number of minutes for a car to get from the intersection to the administration building. This is because time is a continuous variable that can take on any value within a certain range.
For the second question, the type of variable represented in the dotplot is quantitative and discrete. This is because the number of strokes taken by the golfers is a numerical variable and the values represented on the dotplot are distinct and separate.
For the third question, the best description of the distribution based on the given information is that there are two clusters and a gap. This can be observed from the histogram where there are two peaks and a noticeable absence of data between the interval of 25-40 centimeters.
We do not do your homework for you. Although it might take more effort to do the work on your own, you will profit more from your effort. We will be happy to evaluate your work though.
What are your choices?
