In a survey, 31 people were asked how much they spent on their child's last birthday gift. The results were roughly bell-shaped with a mean of $47 and standard deviation of $10. Construct a confidence interval at a 95% confidence level. Give your answers to one decimal place.
The national fire protection association reported that house fires in the United States result in $6.8billion in losses annually. Suppose a random sample of 50 house fires in San Antonio yields a mean loss of $18503. If the population standard deviation is $3300, what is the margin of error for a 95% confidence interval? What would you recommend if the study required a margin of error of $300 or less
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)]
The principal at a large high school claims that students spend at least 10 hours per week doing homework, on average. To investigate this claim, an AP Statistics class selected a random sample of 250 students from their school and asked them how long they spent doing homework during the last week. The sample mean was 10.2 hours and the sample standard deviation was 4.2 hours. Construct and interpret a 95% confidence interval for the mean time that students at this school spent doing homework in the last week. Based on your interval, what can you conclude about the principal's claim? What is your t* value? Remember to use the conservative DF value.
Given the following: Sample Mean = 84.3 Population Variance = 144 Sample size = 35 a. Calculate a 90% confidence interval for the mean. Interpret this interval. b. Calculate a 99% confidence interval for the mean. c. Explain the relationship between Confidence Levels and the resulting intervals.
In a survey, 22 people were asked how much they spent on their child's last birthday gift. The results were roughly bell-shaped with a mean of $50 and standard deviation of $8. Construct a confidence interval at a 90% confidence level.Give your answers to one decimal place.
The Health Care Cost Institute tracks health care expenditures for beneficiaries under theage of 65 who are covered by employer-sponsored private health insurance (Health CareCost Institute website, November 4, 2012). The data contained in the DATAfile namedDrugCost are consistent with the institute’s findings concerning annual prescription costsper employee. Analyze the data using Excel and answer the following questions.a. Develop a 90% confidence interval for the annual cost of prescription drugs.b. Develop a 90% confidence interval for the amount of out-of-pocket expense peremployee.c. What is your point estimate of the proportion of employees who incurred no prescription drug costs?
A community has 60,000 inhabitants, 35,000 of which are female. Of the female population, 525 have been diagnosed with osteoporosis. What is the prevalence rate per 1,00p?
2. A food truck serves lunch every Tuesday and Thursday on the plaza in front of Van Metre Hall on the GMU Arlington campus. The number of customers varies every day, so it wants to order supplies based on the average number of customers served per day. The truck recorded how many customers were served on 40 randomly selected days, and obtained a sample mean and sample standard deviation of 145 and 17, respectively. Construct a 90% confidence interval for the mean number of customers served per day.
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
