In Izmir Univesity of Economics in 2018, from a random sample of 7 students in an introductory finance class that uses group-learning techniques, the mean examination score was found to be 79.55 and the sample standard deviation was 2.5. For anindependent random sample of 8 students in another introductory finance class that does not use group-learning techniques, the sample mean and standard deviation of exam scores were 71.37 and 8.6, respectively. Estimate with 99% confidence the differencebetween the two population mean scores; do not assume equal population variances.Click the icon to view the Student's t distribution table.The 99% confidence interval is from a lower limit ofto an upper limit of(Round to two decimal places as needed.)

How many rounds of golf do those physicians who play golf play per year? A survey of 12 physicians revealed the following numbers: 8, 38, 15, 4, 31, 41, 18, 15, 18, 31, 12, 47 Estimate with 94% confidence the mean number of rounds played per year by physicians, assuming that the population is normally distributed with a standard deviation of 7. Note: For each confidence interval, enter your answer in the form (LCL, UCL). You must include the parentheses and the comma between the confidence limits. Confidence Interval =
We surveyed a random sample of 15 domestic violence victims in Columbus, GA, who used the 911. From this sample, 911 response time from calling to police arrival was 8.5 minutes on average with a standard deviation of 2.7 minutes. From the estimation of the population mean (μ) of the arrival time with a 99% confidence interval, what is the upper limit? (Round off to two decimal places if necessary).

A certain brokerage house wants to estimate the mean daily return on a certain stock. A random sample of 9 days yields the following return percentages: -2.64, 1.58, -1.73, 1.68, -0.09, -1.61, 2.1, -2.44, 1.9 If we assume that the returns are normally distributed, find a 90% confidence interval for the mean daily return on this stock. Then complete the table below. Carry your intermediate computations to at least three decimal places. Round your answers to one decimal place. (If necessary, consult a list of formulas.) What is the lower limit of the confidence interval? What is the upper limit of the confidence interval?
Lori Jeffrey is a successful sales representative for a major publisher of college textbooks. Historically, Lori obtains a book adoption on 36% of her sales calls. Viewing her sales calls for one month as a sample of all possible sales calls, assume that a statistical analysis of the data yields a standard error of the proportion of 0.08. (a) How large was the sample used in this analysis? That is, how many sales calls did Lori make during the month? (c) Using the sampling distribution of p, compute the probability that Lori will obtain book adoptions on 46% or more of her sales calls during a one-month period. (Round your answer to four decimal places.)
A random sample of 13 health maintenance organizations (HMOS) was selected. For each HMO, the co-payment (in dollars) for a doctor's office visit was recorded. The results are as follows. 9, 11, 6, 10, 6, 12, 11, 11, 7, 10, 6, 9, 10 Send data to calculator Send data to Excel Under the assumption that co-payment amounts are normally distributed, find a 99% confidence interval for the mean co-payment amount in dollars. Then find the lower limit and upper limit of the 99% confidence interval. Carry your intermediate computations to at least three decimal places. Round your answers to one decimal place.

HO A clinical trial was conducted to test the effectiveness of a drug for treating insomnia in older subjects. Before treatment, 20 subjects had a mean wake time of 102.0 min. After treatment, the 20 subjects had a mean wake time of 93.1 min and a standard deviation of 22.4 min. Assume that the 20 sample values appear to be from a normally distributed population and construct a 99% confidence interval estimate of the mean wake time for a population with drug treatments. What does the result suggest about the mean wake time of 102.0 min before the treatment? Does the drug appear to be effective? Construct the 99% confidence interval estimate of the mean wake time for a population with the treatment. min < u< min (Round to one decimal place as needed.) - E nd
