A 95% confidence interval for a population proportion p is found to be (0.52, 0.58). What does this mean?
A. There is a 95% probability that the actual value of p is between 52% and 58%.
B. If many simple random samples of the same size were taken from the population, and a confidence interval were constructed for each one, then about 95% of them would contain the actual value of p.
C. 95% of all sample proportions are between 0.52 and 0.58.
D. The standard deviation of the sampling distribution is 0.03.

Solution :
Given that ,
A 95% confidence interval for a population proportion p is found to be (0.52, 0.58) .
This means that ,
If many simple random samples of the same size were taken from the population, and a confidence interval were constructed for each one, then about 95% of them would contain the actual value of p.

A 95% confidence interval for a population proportion was constructed using a sample proportion from a random sample. Which of the following statements are correct? Select all that apply If we were to use a 90% confidence level, the confidence interval from the same data would produce an interval wider than the 95% confidence interval. There is a 95% chance that the 95% confidence interval actually contains the population proportion. We don't...

Let's say we have constructed a 95% confidence interval estimate for a population mean. Which of the following statements would be correct? A. We expect that 95% of the intervals so constructed would contain the true population mean. B. We are 95% sure that the true population mean lies either within the constructed interval or outside the constructed interval. C. Taking 100 samples of the same size, and constructing a new confidence interval from each sample, would yield five intervals...

At a confidence level of 95% a confidence interval for a population proportion is determined to be 0.65 to 0.75. If the sample size had been larger and the estimate of the population proportion the same, this 95% confidence interval estimate as compared to the first interval estimate would be Group of answer choices narrower. the same. wider.

What proportion of adults like pineapple as a pizza topping? A 95% confidence interval for the proportion of adults who say they like pineapple on their pizza was constructed and it was found to be from 0.14 to 0.20. Based on this interval, we know the margin of error must be 0.02. 0.03 It's impossible to answer this question without more information. O 0.06. O 0.05.
