Using Excel or Minitab, determine the sample proportion of the Hospital database under the variable "service" that is "general medical" (category 1). From this statistic, construct a 95% confidence interval to estimate the population proportion of hospitals that are "general medical." What is the point estimate? How much error is there in the interval? (Round z values to 2 decimal places, e.g. 15.25. Round point estimate and confidence interval to 3 decimal places, e.g. 0.251. Round margin of error to 1 decimal place, e.g. 15.2%.)
