Iris Setosa - There are many species of a type of flower called Iris. A botanist wishes to estimate the actual proportion of a particular species of Iris called "Setosa" among the other species of Iris. She collects a random sample of 100 Iris flowers of all species and constructs a 95% confidence interval to be (0.2102, 0.3898). Which of the following statements are true? Select all the that apply.

A 99% confidence interval calculated using the same data will include more plausible values for the actual population proportion.
If the sample size had been double the sample size in the scenario above, then the 95% confidence interval would be half as wide as the one stated above.
If a different sample of the same size were to be selected, then there is a 95% chance that the new sample proportion will lie inside the confidence interval stated above.
If we took several samples of the same size as the scenario given above and constructed 95% confidence intervals for population proportion, then it is reasonable to expect 95% of these confidence intervals to contain the actual population proportion.
If the sample size had been double the sample size in the scenario above, then the 95% confidence interval would be half as wide as the one stated above.
If a different sample of the same size were to be selected, then there is a 95% chance that the new sample proportion will lie inside the confidence interval stated above.

A 90% confidence interval for the population proportion calculated using the same data will be wider than the interval stated above.
If a different sample of the same size were to be selected and a 95% confidence interval constructed, then there is a 95% chance that the actual population proportion will lie inside the new confidence interval.
