A95% 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. the sample proportion must lie in the 95% confidence interval. there is a 95% chance that the 95% confidence interval actually contains the population proportion. we don't know if the 95% confidence interval actually does or doesn't contain the population proportion. the population proportion must lie in the 95% confidence interval.

All but last statement are correct.

Step-by-step explanation:

True. Confidence interval gets wider as the confidence level decreases.  

True. Confidence interval is constructed around sample mean.

True. Constructing 95%. confidence interval for a population proportion using a sample proportion from a random sample means the same as the above statement.

True. There is 95% chance that confidence interval contains population proportion and 5% chance that it does not.

False. There is 95% chance that population proportion lies in the confidence interval.

correct answer:

a + bi

y = 2x

step-by-step explanation:

if you divide each number in the sequence, you'll see that they all have a multiple factor of 2. each number in the series, and any other numbers which may continue, will be multiplied by 2. therefore, y is the next number in the sequence, and x is the current one, so, our formula will be y = 2x.
