1. To understand the cooking and diet patterns of Americans, a research company surveyed 12,340 American adults (age 18 and older) during the year 2014 and asked about a variety of factors including age, gender, yearly income (in US $), and the number of hours spent cooking each week. Answer the following questions regarding the context of the survey: a. WHO is being measured? (What is the sample?) b. WHAT is being measured? (What are the variables?) For each variable, identify whether it is quantitative or categorical.

Dental health issues remain a barrier to attendance, as evidenced by a 2010 Los Angeles School Attendance Review Board (SARB), which lists dental health, along with homelessness, in the top barriers to attendance. The Dental Hygiene program at West Los Angeles College collects data on its clinic patients to help instructors and students better understand their patient population. From July 2017 to December 2019 the program treated 3421 patients. Students were asked to analyze a random sample of 127 patients from that time period and found that 36.4% had severe periodontal disease (infections and inflammation of the gums and bone that surround and support the teeth). Identify the population: Identify the sample: Identify the parameter of interest: Identify the statistic:
