2. According to the website www.costofwedding.com, the average cost of catering a wedding is $100 per person. Recently, in a random sample of 30 weddings in the U.S. it was found that the average catering cost was $110, with a standard deviation of $12. Assume that the distribution of catering costs is approximately normal. A. Construct a 99% confidence interval for the population mean catering cost. (Check the conditions for the procedure, determine the t* value, and show the calculations for the margin of error and confidence interval.) B. Explain what the 99% confidence level means – what does it mean to be 99% confident of the estimate? C. Would a 95% confidence interval be narrower or wider than the 99% confidence interval? Explain. (You do not need to construct the 95% interval.)

A study by the International Coffee Organisation found that persons aged 30 – 59 drank an average of 0.57 cups of coffee per day. Assuming that the sample size is 200 with a sample standard deviation of 0.4 cups, construct a 95% confidence interval for the population mean cup of coffee. Interpret your answer.
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? The test statistic is: __________________(please round to two decimal places)The p-value:___________________________ for this hypothesis test is: (please round to four decimal places)(c) Please comment on the primary thing that is wrong about the following statement: There is sufficient evidence…

Suppose that your sample size is 30 and that you wish to construct a 95% confidence interval. Your sample standard deviation is 40.9. Estimate your margin of error (MOE) using this information and the t-distribution table. Estimate your response to the first decimal point.
In a random sample of 17 people, the mean commute time to work was 30.2 minutes and the standard deviation was 7.1 minutes. Assume the population is normally distributed and use a t- distribution to construct a 95% confidence interval for the population mean y. What is the margin of error of y? Interpret the results.
A researcher is studying the average cost of traveling for a college student. As part of their research, they would like to learn more about the average yearly money spent to travel to and from home by air. In a random sample of 130 students, the mean travel cost by air was $1180 with a standard deviation of $535. Use these sample data to answer the following questions. Construct a 95% confidence interval to estimate the mean travel cost by air. Remember to include all relevant Minitab output and to identify your answer. You should not need to do any calculations by hand.
A survey of 73 randomly selected homeowners finds that they spend a mean of $74 per month on home maintenance. Construct a 95% confidence interval for the mean amount of money spent per month on home maintenance by all homeowners. Assume that the population standard deviation is $16 per month. Round to the nearest cent.
Use the following information to answer the question. According to the website ww.costofwedding.com, the average cost of flowers for a wedding is $698. Recently, in a random sample of 40 weddings in the U.S. it was found that the average cost of the flowers was $734, with a standard deviation of $102. On the basis of this, a 95% confidence interval for the mean cost of flowers for a wedding is $701 to $767.Does the confidence interval provide evidence that the mean cost of flowers for a wedding has increased? a) Yes b) No
