which meal breakfast lunch or dinner is your favorite meal of the day
during which month do you prefer to go on vacation
do you prefer white bread of healthy whole wheat bread
Do you prefer white bread or healthy whole wheat bread? This survey question is biased as it assumes that white bread is not healthy when it may not necessarily be true.

game wardens use experiments to help determine the number of deer in the state of north calorina soppose 120 deers are cought tagged and realeased back in to the wild a month later 800 deers are caught 16 have tags use this info to estimate the number of deers in north calorina
800
1200
1920
6000
To estimate the number of deer in North Carolina using this information, we can use a proportion:
Number of tagged deer in first sample / Total number of deer in first sample = Number of tagged deer in second sample / Total number of deer in the population
Plugging in the numbers we have:
120 / X = 16 / 800
Cross-multiplying, we get:
120 * 800 = 16 * X
X = (120 * 800) / 16
X = 6,000
Therefore, we can estimate that there are approximately 6,000 deer in the state of North Carolina. Answer: 6000.
is 1 2 2 3 1 3 a positive trend
There is not a clear positive trend in the sequence 1 2 2 3 1 3. A positive trend would indicate that each consecutive term is larger than the previous term. In this sequence, there is an increase from 1 to 2, but then the next value stays the same at 2, followed by a further increase to 3. The trend seems a bit irregular.
jamal found the mean hourly wage of employees at his compony using the data in the table in a report he started the typicall salary at the company is about 23.00 per hour how is this misleading
Without the actual value of the mean hourly wage it is hard to conclusively say that the statement is misleading, but if the mean hourly wage is actually lower than $23.00 per hour, then the statement that "the typical salary at the company is about $23.00 per hour" is misleading.
Additionally, the mean hourly wage is just an average and does not tell us about the spread or distribution of wages. Some employees may be making much less than the mean hourly wage, while others may be making much more. Therefore, relying solely on the mean hourly wage to make a generalization about typical wages at the company may not provide an accurate representation of the salaries of employees.
which is the best display for the list of the number of tornados in the united states each year if you want to be able to identify the mode
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 would be a histogram.
A histogram is a graphical display of data that uses bars to show the frequency of data items in successive numerical intervals. It is particularly useful when data needs to be grouped into classes, and the relative frequency of each class is to be displayed. By grouping the number of tornadoes into classes (e.g. 0-10, 11-20, 21-30, etc.) and constructing a histogram, the mode (or modes, if there is more than one) can be easily identified as the class with the highest frequency.
john asked 30 randomly selected adult restaurant customers about their choice of beverages if the restaurant serves 200 adults per day estimate the number of who will choose coffee to drink
Assuming that the 30 randomly selected customers are representative of the larger population, we can use the proportion of customers who chose coffee in the sample to estimate the number of adults who will choose coffee to drink out of the 200 adults per day.
If, for example, 12 out of the 30 randomly selected customers chose coffee, we can assume that the proportion of customers who chose coffee in the larger population is:
12/30 = 0.4
We can then estimate the number of adults out of 200 who will choose coffee by multiplying 0.4 by 200:
0.4 x 200 = 80
Therefore, based on this sample of 30 customers, we can estimate that approximately 80 adults out of 200 will choose coffee to drink at the restaurant.

Without knowing how many of the 30 randomly selected adult customers chose coffee, it is impossible to estimate the number of adults who will choose coffee to drink out of the 200 adults per day.
The information provided in the question is not enough to determine an estimate with any reliability.
john asked 30 randomly selected adult restaurant customers about their choice of beverages 18 costemers said cofeeis their favorite if the restaurant serves 200 adults per day estimate the number of who will choose coffee to drink
100
110
120
130
If 18 out of 30 randomly selected customers said coffee is their favorite, we can assume that the proportion of customers who choose coffee in the larger population is:
18/30 = 0.6
We can estimate the number of adults out of 200 who will choose coffee by multiplying 0.6 by 200:
0.6 x 200 = 120
Therefore, based on this sample of 30 customers, we can estimate that approximately 120 adults out of 200 will choose coffee to drink at the restaurant.
Therefore, the estimate is 120.
you are surveying students to find ut their opinions of the quality of food served in the cafetireia you deside to poll only those students who buy hot lunch on a particular day is your sample random? explain
No, the sample of students who buy hot lunch on a particular day is not random because it only represents a specific group of students who are buying hot lunch on that day. This sample is a convenience sample, which is a non-random technique of selecting a sample based on what is convenient or readily available.
If the purpose of the survey is to obtain information on the opinions of students about the quality of food served in the cafeteria, then it is important to select a random sample of students to ensure the sample is representative of the larger population of students. A random sample would provide a better representation of the opinions of all students, rather than just those who chose to buy hot lunch on a particular day.
To obtain a random sample, a possible method would be to randomly select a group of students from the entire student population and ask for their opinions on the quality of food served in the cafeteria. This would ensure that all students had an equal chance of being selected to give their opinions.
