Suppose a study was conducted of community colleges in California 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 $1,440 and the standard deviation was $267. Use this information to construct and interpret a 92% confidence interval for the true average tuition of all California community colleges. Make sure to check any 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 [i.e. (12.345, 45.678)]
Several years ago, 35% of parents who had children in grades K-12 were satisfied with the quality of education the students receive. A recent poll asked 1,195 parents who have children in grades K-12 if they were satisfied with the quality of education the students receive. Of the 1,195 surveyed, 483 indicated that they were satisfied. Construct a 99% confidence interval to assess whether this represents evidence that parents' attitudes toward the quality of education have changed. What are the null and alternative hypotheses? Ho: p versus H,: p (Round to two decimal places as needed.)
In a survey funded by the UW school of medicine, 750 of 1000 adult Seattle residents said they did not believe they could come down with a sexually transmitted infection (STI). Construct a 95% confidence interval estimage of the proportion of adult Seattle residents who don't believe they can contract an STI. (Use a z score of 1.96 for your computations.)

A trade magazine routinely checks the drive-through service times of fast-food restaurants. A 95% confidence interval that results from examining 734 customers in one fast-food chain's drive-through has a lower bound of 169.8 seconds and an upper bound of 173.4 seconds. What does this mean? Choose the correct answer below. O A. One can be % confident that the mean drive-through service time of this fast-food chain is between seconds and seconds. O B. There is a % probability that the mean drive-through service time of this fast-food chain is between seconds and seconds. O C. The mean drive-through service time of this fast-food chain is seconds % of the time. O D. One can be % confident that the mean drive-through service time of this fast-food chain is seconds.
Several years ago, 46% of parents who had children in grades K-12 were satisfied with the quality of education the students receive. A recent poll asked 1,135 parents who have children in grades K-12 if they were satisfied with the quality of education the students receive. Of the 1,135 surveyed, 474 indicated that they were satisfied. Construct a 90% confidence interval to assess whether this represents evidence that parents' attitudes toward the quality of education have changed. What are the null and alternative hypotheses? Ho: P versus H₁: p (Round to two decimal places as needed.) (…)
A study is conducted by a physical therapist to determine whether there is a difference in the proportion of men and women in the U.S. that participate in regular sustained physical activity. It is found that 22% of menout of 550 and 19.5% of women out of 450 participated in regular sustained physical activity. Construct a 90% confidence interval for the difference in proportions of men and women that participate in regular sustained and state your conclusion.
A trade magazine routinely checks the drive-through service times of fast-food restaurants. A 95% confidence interval that results from examining 502 customers in one fast-food chain's drive-through has a lower bound of 165.9 seconds and an upper bound of 169.5 seconds. What does this mean? Choose the correct answer below. O A. One can be 95% confident that the mean drive-through service time of this fast-food chain is 167.7 seconds. OB. There is a 95% probability that the mean drive-through service time of this fast-food chain is between 165.9 seconds and 169.5 seconds. O C. One can be 95% confident that the mean drive-through service time of this fast-food chain is between 165.9 seconds and 169.5 seconds. OD. The mean drive-through service time of this fast-food chain is 167.7 seconds 95% of the time.
A survey of 3737 randomly selected homeowners finds that they spend a mean of $73$73 per month on home maintenance with a standard deviation of $10$10 per month.

Several years ago, 45% of parents who had children in grades K-12 were satisfied with the quality of education the students receive. A recent poll asked 1,025 parents who have children in grades K-12 if they were satisfied with the quality of education the students receive. Of the 1,025 surveyed, 484 indicated that they were satisfied. Construct a 99% confidence interval to assess whether this represents evidence that parents' attitudes toward the quality of education have changed.
