Two questions:
what is the confidence level we are looking at?
also the p-value of .240.24? Is that a mistake in typing or is it .240 to the 24 decimal?
Generally, if the p-value is less than the confidence level (alpha) you reject the null hypothesis. The null hypothesis here is that the ads didn't nothing to help.
For instance, if the p-value were .240 and the alpha was .05 you would reject the null hypothesis and say that the ads may have had an effect on the outcome.
Answer:
A. Public good
B. Common resource
C. Private good
Explanation:
A. Here, a fountain in the park is a public good as it is freely available to everyone. Its consumption is non-rival and non-excludable. Everyone can consume it without reducing the consumption of others.
B. A dock on the lake is not a public good because people cannot use it freely. To use it people need to pay so those who don't pay can be excluded. Too many people cannot use it at the same time. So we can say it is a common resource whose consumption is expensive.
C. A new drone is a private good. Its use depends on ownership if one person is using it at a time another person cannot. People can be excluded from using it based on ownership.
I would say that is right because it depends on what the problem is and if you want suggestions on how to fix the problem or if the problem is just between a few people.
I hope that helped!
