At one excavation site a sample of 592 370 were identified as Santa Fe black on-white. the proportion of Santa Fe black on white potsherds at the excavation site. Find a point estimate for p. (Round your anawer to four decimal places.) a) Let (b) find a 95% confidence interval for p. (Round your answers to three decinal places.) lower imit upper limit

Explanation / Answer

The statistical software output for this problem is:

One sample proportion summary confidence interval:
p : Proportion of successes
Method: Standard-Wald

95% confidence interval results:

Hence,

a) Point estimate = 0.6250

b) 95% confidence interval:

Lower limit = 0.586

Upper limit = 0.664

Proportion Count Total Sample Prop. Std. Err. L. Limit U. Limit p 370 592 0.625 0.019897329 0.58600195 0.66399805
