The following table represents the age when an award was won. Use this table to answer the following questions     Class limits Frequency 10-19 31 20-29 33 30-39 13 40-49 2 50-59 6 60-69 2 70-79 2   Identify the lower class limits   [1], [2], [3], [4], [5], [6], [7]   (Type integers or decimals. Do not round. Use ascending​ order (smallest to biggest).)    

Use the following prompt to answer the next 4 questions:   A research institute poll asked respondents if they felt vulnerable to identity theft. In the​ poll, 901 people were surveyed and  538 who said​ “yes.”  Use a  90% confidence level (critical value is 1.65)

b. Find the margin of error E.  E=  (round to three decimal places as needed)
