Which is the best display for the set of the number of tornadoes in the United States each year , If you want to be able to identify the mode?
a) histogram with intervals of
b) frequency table with intervals of 3
c) line pot
d) line graph
WAY TO LATE BUT.....Its B
Hahaha yep a bit late but Kang Seulgi is right *O*
b k
frequency table with intervals of 3
That's correct! A frequency table with intervals of 3 would allow you to group the data and identify the mode more easily. With a histogram, the width of the bars can affect the appearance of the mode, while a line plot or graph wouldn't allow you to group the data for easier identification of the mode.
Not please help

Kendall asked 40 randomly-selected seniors at his high school about their plans for after they graduated. (1 point)
Twenty-nine students said they planned to go to college. If there are 380 seniors at Kendall's high school,
estimate the number who plan to go to college.
0245
0275
0310
0330
We can use proportion to estimate the number of seniors who plan to go to college.
Let's set up the proportion:
number of seniors who plan to go to college / total number of seniors = number of sample who plan to go to college / total number of samples
Plugging in the given values, we get:
29 / x = 40 / 380
To solve for x, we can cross-multiply and simplify:
29 * 380 = 40 * x
11020 = 40x
x = 11020 / 40
x = 275.5
Since we're dealing with whole people, we round up to the nearest whole number:
x ≈ 276
Therefore, we estimate that around 276 seniors at Kendall's high school plan to go to college.
The closest answer choice to this estimate is 275.
Which is the best display for the list of the number of tornadoes in the United States each year, if you
want to be able to identify the mode?
O histogram with intervals of 5
O frequency table with intervals of 3
Oline plot
Oline graph
The best display for the list of the number of tornadoes in the United States each year, if you want to be able to identify the mode, is a histogram with intervals of 5.
A histogram with intervals of 5 would allow you to group the tornado data into intervals and determine the largest interval, which would represent the mode.
While a frequency table with intervals of 3 would also group the data, it wouldn't provide as much detail as a histogram, which would allow you to see the distribution of the data. A line plot or line graph wouldn't work as well, since they aren't used for displaying data with a wide range of values.
So what’s the answer
The correct answer is:
Histogram with intervals of 5
Jamal found the mean hourly wage of employees at his company using the data in the table. In a report
he stated, "The typical salary at the company is about $23.00 per hour." How is this misleading?

© The mean is not a good measure of the salaries because five employees have salaries far above the other fifteen
employees salaries.
O The mean of the data is not about $23.00.
O Jamal should always use the highest wage
O His statement is not misleading.
The statement "The typical salary at the company is about $23.00 per hour" is misleading because it refers to the mean hourly wage, which is not the same as the typical salary. The mean is affected by any outliers in the data, and in this case, five employees have salaries that are far above the other fifteen employees' salaries. This means that their high salaries will skew the mean wage upwards, making it higher than the typical or median salary.
Therefore, the correct answer is:
The mean is not a good measure of the salaries because five employees have salaries far above the other fifteen employees' salaries.
Are you correct all the way?
Or, are you incorrect.
