Suppоse а study wаs cоnducted оf community colleges in Cаlifornia to determine the average cost of tuition for in-state students. The study consisted of 45 community colleges from California. Based on the sample data, the average tuition was $1,410 and the sample standard deviation was $252. Use this information to construct and interpret a 92% confidence interval for the true average tuition of all California community colleges. Make sure to address the following in your response: Check any and all relevant assumptions and state how you determined whether or not they were satisfied (Be as specific as possible) Make sure to type your confidence interval in an interval format with each bound rounded to the nearest whole number. Also make sure to specify what method you used to construct this interval (e.g. Where did you go on your calculator/device or what are the values/calculations you used to find the bounds) Make sure to include an interpretation in context of the given problem
A mаth prоfessоr wаs interested in figuring оut whether students tаking mathematics classes at his school preferred to take them online or face to face. He decided to randomly survey students taking mathematics classes that semester. He ended up surveying 120 students who were taking math classes that semester, and 37 of them stated that they preferred taking their math classes online while 83 of them preferred taking them face to face. Construct and interpret a 95% confidence interval for the true proportion of students at the school that prefer to take math classes face to face. Make sure to address the following in your response: Check any and all relevant assumptions and state how you determined whether or not they were satisfied (Be as specific as possible) Make sure to type your confidence interval in an interval format with each bound rounded to 3 decimal places [For example, (0.123, 0.456)] Also make sure to specify what method you used to construct this interval (e.g. Where did you go on your calculator/device or what are the values/calculations you used to find the bounds) Make sure to include an interpretation in context of the given problem

He ended up surveying 130 students who were taking math classes that semester, and 35 of them stated that they preferred taking their math classes online while 95 of them preferred taking them face to face. Construct and interpret a 96% confidence interval for the true proportion of students at the school that prefer to take math classes face to face.
