Question 3 9 pts Academic advising: In 2014 the Community College Survey of Student Engagement reported that 32% of the students surveyed rarely or never use academic advising services. Suppose that in reality, 42% of community college students rarely or never use academic advising services at their college. In a simulation we select random samples from this population. For each sample we calculate the proportion who rarely or never use academic advising services What is the smallest sample in the...

In a sample of 20 students enrolled in a hybrid course one that contains both online and classroom instruction), the mean number of hours it took students to meet the online course objectives was 53.7 with a standard deviation of 12.1. a.) What is the best point estimate of the mean number of hours it takes students to meet online course objectives? b.) How many degrees of freedom will be used for the given sample size? c.)

We wish to survey students at community college campuses to find out what percent of them prefer taking online classes. We want 95% confidence, and we want the sample percentage to be within 5 percentage points of the population percentage. How large a sample do we need? Round up to the nearest integer (for example, 92.15 would be rounded up to 93).

You are to estimate the average number of hours that students who are planning to enroll at a college in the fall semester will be taking. You don’t know the standard deviation (or variance), but from previous semesters you have an idea about the range. Historically, the lowest number of hours taken is 1 (usually a PE course). At the other end of the spectrum, the most hours a student has ever been enrolled for is 24. Using industry convention,...

A college has 25000 students. Based on student personal information data, approximately 45 percent are Democrats. A simple random sample of 900 households were selected for a survey. The percentage of Democrats in the sample will be around 45 and 1.65 give or take or so. Estimate the chance that between 42.45 percent and 47.55 percent of the students in the sample are Democrats _____ Please show work. Thank you.

Software instruction: A hybrid course is one that contains both online and classroom instruction. In a study performed at Middle Georgia State College, a software package was used as the main source of instruction in a hybrid college algebra course. The software tracked the number of hours it took for each student to meet the objectives of the course. In a sample of 44 students, the mean number of hours was 80.5, with a standard deviation of 51.4. Part: 0/2...

Suppose a poll conducted at a certain college during their most recent spring semester asked 695 college students whether or not a privately owned dining hall should be allowed on campus. The response "Yes, it should" was selected by 38% of the respondents. (a) Suppose the researchers who conducted the poll reported "For results based on the total college population, once can say with 95% confidence that the margin of sampling error is no greater than 4 percentage points." Explain...
