In late 2011 and early 2012, the Universal Health Care Foundation of Connecticut surveyed small business owners across the state that employed 50 or fewer employees. The purpose of the study was to gain insight on the current small business health-care environment. Small business owners were asked if they offered health-care plans to their employees and if so, what portion (%) of the employee monthly health-care premium the business paid. The following frequency distribution was formed to summarize the portion of premium paid for 89 (out of 311) small businesses who offer health-care plans to employees:

a. What percentage of small businesses pays less than 26% of the employee monthly health-care premium?
b. What percentage of small businesses pays between 26% and 75% of the employee monthly health-care premium?
c. What percentage of small businesses pays more than 75% of the employee monthly health-care premium?
