Snoop Incorporated is a firm that does market surveys. The Rollum Sound Company hired Snoop to study the age distribution of people who stream music. To check the Snoop report, Rollum used a random sample of 519 customers and obtained the following data. Customer Age (yrs) Percent of Customers from Snoop Report Number of Customers from Sample Less than 14 12% 98 14 - 18 29% 129 19 - 23 11% 55 24 - 28 10% 37 29 - 33 14% 83 More than 33 24% 117 LA USE SALT Using a 1% level of significance, test the claim that the distribution of customer ages in the Snoop report agrees with that of the sample report.
