**Title: Educational Attainment by Social Class Based on GSS 2018 Data**---**Text:**This section explores the average years of education reported by different social classes, as gathered from the General Social Survey (GSS) 2018.**Table: Average Years of Education by Social Class**| Social Class | Mean | Standard Deviation | N ||---------------|------|--------------------|-----|| Lower class | 12.19| 3.08 | 102 || Working class | 13.16| 2.93 | 523 || Middle class | 14.60| 2.88 | 498 || Upper class | 15.21| 3.01 | 34 |- **Mean**: The average number of years of education completed.- **Standard Deviation**: A measure of the amount of variation or dispersion of educational years within each class.- **N**: The number of respondents in each social class.**Exercises:**a. Construct the 95% confidence interval for the mean number of years of education for lower- and working-class respondents.b. Construct the 99% confidence interval for the mean number of years of education for lower-class and middle-class respondents.c. As our confidence in the result increases, how does the size of the confidence interval change? Explain why this is so.---**Explanation of Exercises:**- **Confidence Interval**: This is a range of values that is likely to contain the true mean of the population with a certain level of confidence (e.g., 95% or 99%).- A higher confidence level, such as 99%, will result in a wider confidence interval compared to a lower level, like 95%. This occurs because more certainty requires accounting for more variability, thus expanding the interval to ensure it captures the true mean.This data provides insights into educational disparities among different social classes and serves as a foundation for statistical analysis exercises involving confidence intervals.

College tuition: The mean nual tuition and fees in the 2013-2014 academic year for a sample of 13 private colleges in California was $38,500 with a standard deviation of $7000.

Intellectual development (Perry) scores were determined for 21 students in a first-year, project-based design course. (Recall that a Perry score of 1 indicates the lowest level of intellectual development, and a Perry score of 5 indicates the highest level.) The average Perry score for the 21 students was 3.27 and the standard deviation was .40. Apply the confidence interval method to estimate the true mean Perry score of all undergraduate engineering students with 90% confidence. Interpret the results.

3. Based on information from the U.S. Census Bureau, the mean travel time to work (mins), for all workers 16 years and older was 25.3 minutes. A large company with offices in several states randomly sampled 100 of its workers to ascertain their commuting times. The sample mean was 23.9 minutes, and the population standard deviation is 6.39 minutes. At the level of significance, can it be concluded that the mean commuting time is less for this particular company? H. : H :

2. University researchers claim that the average enrollment at four-year colleges is higher than two-year community colleges. Two surveys are undertaken at 35 four-year universities and 35 two-year colleges. The mean enrollment at the four-year institutions was 5,466 with a standard deviation of 8,191. The average enrollment at the two-year schools was 5,068 with a standard deviation of 4,777. Using a 95% confidence level, are the findings of the surveys consistent with the university researchers’ claim? 2. Does the null hypothesis reject H0 or fail to reject H0?
Fuel efficiency of Prius: Fueleconomy.gov, the official US government source for fuel economy information, allows users to share gas mileage information on their vehicles. The histogram below shows the distribution of gas mileage in miles per gallon (MPG) from 14 users who drive a 2012 Toyota Prius. The sample mean is 53.3 MPG and the standard deviation is 5.2 MPG. Note that these data are user estimates and since the source data cannot be verified, the accuracy of these estimates are not guaranteed. (a) The EPA claims that a 2012 Prius gets 50 MPG (city and highway mileage combined). Do these data provide strong evidence against this estimate for drivers who participate on fueleconomy.gov?
