Determine the point estimate of the population proportion,the margin of error for the following confidence interval,and the number of individuals in the sample with the specified characteristic, x, for the sample size provided. Lower bound=0.691, upper bound=0.909, n=1500. The number of individuals in the sample with the specified characteristic is? Round to the nearest integer as needed

1500*(0.909-0.691) =448.5
