After students were not doing so well in her english class, Mrs. Jones decided to try a different approach and use verbal positive reinforcement at least once every hour. Use the following results to find a 99 % confidence interval for the true mean change in the students' test scores after Mrs. Jones started using positive reinforcement. Assume that the population distribution of the paired differences is approximately normally distributed. Round to one decimal place.

Next Question A statistics instructor randomly selected four bags of oranges, each bag labeled 10 pounds, and w that the distribution of weights is Normal. Find a 95% confidence interval for the mean weight of all bags of oranges. Use technology for your calculations. Answer parts a and b ley weighed 9.3, 9.1, 9.5, and 9.6 pounds. D Assume below. a. Choose the correct interpretation of the confidence interval below and, if necessary, fill in the answer boxes to complete your choice. O A. We are 95% confident that the sample mean is between and O B. There is a 95% chance that all intervals will be between and O C. We are 95% confident the population mean is between and O D. The requirements for constructing a confidence interval are not satisfied. (Type integers or decimals rounded to the nearest thousandth as needed. Use ascending order.) b. Does the interval capture 10 pounds? Is there enough evidence to reject the null hypothesis that the population mean weight is 10 pounds? Explain…

You are interested in finding a 90% confidence interval for the mean number of visits for physical therapy patients. The data below show the number of visits for 13 randomly selected physical therapy patients. Round answers to 3 decimal places where possible. 15 26 28 28 14 11 18 20 5 19 15 14 19 a. To compute the confidence interval use a Correct distribution. b. With 90% confidence the population mean number of visits per physical therapy patient is between and visits. c. If many groups of 13 randomly selected physical therapy patients are studied, then a different confidence interval would be produced from each group. About percent of these confidence intervals will contain the true population mean number of visits per patient and about percent will not contain the true population mean number of visits per
