If n = 580 and X = 464, construct a 90% confidence interval for the population proportion, p.

Give your answers to three decimals

< p <

And the 90% confidence interval would be given (0.773;0.827).

Step-by-step explanation:

The information given is:

represent the number of individuals with the characteristic

the sample size

The confidence interval would be given by this formula

For the 90% confidence interval the value of and , the critical value for this case is:

And replacing into the confidence interval formula we got:

And the 90% confidence interval would be given (0.773;0.827).
