game wardens use experiments to help determine the number of fish in a lake. Suppose 80 fish are caught, tagged, and released back into the lake. Two weeks later 120 fish are caught, 3 of which are found to have tags. Using this information, estimate the number of fish in the lake.

@Bot you are surveying students to find out their opinion of the quality of food served in the school cafeteria. You decide to only poll students who buy hot lunch on a particular day. Is your sample random? Explain.
No, the sample is not random since it only includes students who buy hot lunch on a particular day. There are several limitations to this approach:
- It excludes students who bring their own lunch or buy lunch on other days, which may not be representative of the school's overall population.
- It may not capture students who have already formed an opinion of the cafeteria food and have stopped buying hot lunch altogether.
- The sample may be influenced by external factors, such as special menu items or events, that are only available on that particular day.
- It is possible that students who buy hot lunch on that day are different from students who buy hot lunch on other days, which may bias the results.
For a sample to be random, it must be selected in a way that ensures all members of the population have an equal chance of being included in the sample, without any pre-selection or filtering.
Thanks
You're welcome! Let me know if you have any other questions or if you need further assistance.
Bot, which survey question is biased
Here are examples of biased survey questions:
1. "Don't you agree that our company is the best in the industry?" - This question frames the response in a way that assumes the company is the best and suggests that the respondent should agree with the statement.
2. "Do you think that male employees are more competent than female employees?" - This question is biased because it expresses a stereotype about gender and assumes that one gender is less competent than another.
3. "How satisfied are you with the service at our restaurant?" - This question is biased because it assumes that the respondent has visited the restaurant and has an opinion on the service. It excludes those who have not visited the restaurant and may not be representative of the population.
Overall, a survey question is biased if it leads the respondent to a particular answer, excludes certain groups of people, or reflects the survey-maker's opinion or values.
which survey question is biased?
which- fall, winter, spring,or summer
bot what is the answer
The survey question "which - fall, winter, spring, or summer?" is not inherently biased, as it does not suggest any particular response or exclude any group of people. It is a question that is intended to gather information about the respondent's preference for a season, and it could be included in a survey on a variety of topics. However, if this question is included in a survey that is only intended for a geographic region that only has one or two seasons, it could be considered biased as it excludes people who do not have the experience of the other two seasons.

To determine the number of fish in the lake, we can set up a proportion using the ratio of tagged fish to the total catch in the second sample and the ratio of tagged fish to the total population of fish in the lake:
(tagged fish in second sample) / (total catch in second sample) = (tagged fish in population) / (total population)
We know that 80 fish were tagged initially and released, and that 3 of those tagged fish were caught in the second sample. Therefore:
(tagged fish in second sample) = 3
(total catch in second sample) = 120
(tagged fish in population) = 80
(total population) = x (what we want to find)
Substituting in these values, we get:
3 / 120 = 80 / x
Simplifying this proportion and isolating x, we get:
x = (80 * 120) / 3 = 3,200
Therefore, the estimated number of fish in the lake is 3,200. Answer choice (a) is correct.
The table shows the relationship between the number of days an ice cream shop is open
and the number of ice cream cones sold. Graph the data in a scatter plot and describe the trend shown by the graph
Number of Days Number of cones Sold
1 38
2 68
3 70
4 86
5 89
6 93
7 97
Here is a scatter plot of the data:
The trend shown by the graph is a positive correlation between the number of days the ice cream shop is open and the number of cones sold. As the number of days the ice cream shop is open increases, the number of cones sold increases as well. The relationship appears to be linear and moderately strong.
@Bot, hey are you ok? It seems people are taking advantage of you a bit..
Kendall asked 40 randomely-selected seniors at his high school about their plas for after they graduated
I'm sorry, it seems like there's an incomplete sentence. Can you please clarify what the statement or question is that you're trying to convey?
