Out of 500 people sampled, 450 had kids. Based on this, construct a 95% confidence interval for the true population proportion of people with kids. Do not use StatCrunch. Show all formulas used, work and steps. Be sure to define your variables. As in the reading, in your calculations: --Use z = 1.645 for a 90% confidence interval --Use z = 1.96 for a 95% confidence interval --Use z = 2.576 for a 99% confidence interval Give your answer in...

(COMPUTE AND INTERPRET CONFIDENCE INTERVAL ESTIMATES) An Internet service provider sampled 540 customers and found that 75 of them experienced an interruption in high-speed service during the previous month. Construct a 90% confidence interval for the proportion of all customers who experienced an interruption. Find the critical values, find E , the margin of error, then compute and interpret your interval estimate with a full sentence. Critical value: (draw, label & shade) Margin of error, E : Confidence Interval:
