A biologist studying environmental pollutants finds that 32% of a random sample of tuna has high levels of mercury in their blood. The 90% confidence interval is found to be (0.23,0.41).

Which of the following is the correct interpretation for this confidence interval?

a) 90% of the time, the sample proportion of tuna with high levels of mercury in their blood will be in the interval

b) we are 90% confident that the sample proportion of tuna with high levels of mercury in their blood will be within the interval

c) we are 90% confident that the population proportion of tuna with high levels of mercury in their blood will be within the interval

d) there is a 90% probability that the population proportion tuna with high levels of mercury in their blood will be within the interval

A random sample of 1,175 people in a certain country were asked whether they thought climate change was a problem. The sample proportion of those who think climate change is a problem was calculated, and a 95 percent confidence interval was constructed as (0.146, 0.214). Which of the following is a correct interpretation of the interval? a) We are 95 percent confident that any sample of 1,175 people will produce a sample proportion between 0.146 and 0.214. B)We are 95...
