**Clinical Trial on Drug Effectiveness for Insomnia in Older Subjects**A clinical trial was conducted to assess the effectiveness of a drug intended for treating insomnia in older subjects. Below are the results and analysis:**Study Details:**- **Sample Size:** 21 subjects- **Mean Wake Time Before Treatment:** 104.0 minutes- **Mean Wake Time After Treatment:** 78.3 minutes- **Standard Deviation:** 20.3 minutes**Objective:**Construct a 99% confidence interval estimate of the mean wake time for a population with the drug treatment. **Instruction:**Calculate the 99% confidence interval for the mean wake time and round to one decimal place. **Analysis Question:**What do these results suggest about the mean wake time of 104.0 minutes before the treatment? Does the drug appear to be effective?**Conclusion:**- The calculation of the confidence interval will help determine if the mean wake time after treatment significantly differs from the mean of 104.0 minutes before the treatment.- A reduction in the mean wake time suggests the drug treatment is effective.**Interactive Section:**Fill in the confidence interval and interpret the result:- [ ] min < μ < [ ] min **Question:**What does the confidence interval suggest about the mean wake time of 104.0 minutes before the treatment?- The confidence interval [ ] the mean wake time of 104.0 minutes before the treatment, indicating whether the means before and after the treatment differ.- This result suggests that the drug treatment [].*Note:* Interactive elements allow users to input and evaluate their own answers based on the trial data.

A clinical trial was conducted to test the effectiveness of a drug for treating insomnia in older subjects. Before treatment, 16 subjects had a mean wake time of 103.0 min. After treatment, the 16 subjects had a mean wake time of 94.3 min and a standard deviation of 21.5 min. Assume that the 16 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 103.0 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.
A clinical trial was conducted to test the effectiveness of a drug for treating insomnia in older subjects. Before treatment, 17 subjects had a mean wake time of 103.0 min. After treatment, the 17 subjects had a mean wake time of 97.9 min and a standard deviation of 23.6 min. Assume that the 17 sample values appear to be from a normally distributed population and construct a 95% 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 103.0 min before the treatment? Does the drug appear to be effective? Construct the 95% confidence interval estimate of the mean wake time for a population with the treatment. min < µ< min (Round to one decimal place as needed.)
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.
In a test of the effectiveness of garlic for lowering cholesterol, 42 subjects were treated with garlic in a processed tablet form. Cholesterol levels were measured before and after the treatment. The changes (before - after) in their levels of LDL cholesterol (in mg/dL) have a mean of 3.9 and a standard deviation of 15.3. Construct a 99% confidence interval estimate of the mean net change in LDL cholesterol after the garlic treatment.

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 105.0 min. After treatment, the 20 subjects had a mean wake time of 82.5 min and a standard deviation of 22.5 min. Assume that the 20 sample values appear to be from a normally distributed population and construct a 90% confidence interval estimate of the mean wake time for a population with drug treatments.

A clinical trial was conducted to test the effectiveness of a drug for treating insomnia in older subjects. Before treatment, 23 subjects had a mean wake time of 102.0 min. After treatment, the 23 subjects had a mean wake time of 77.3 min and a standard deviation of 20.7 min.

A company that manufactures baseball bats believes that its new bat will allow players to hit the ball 30 feet farther than its current model. The owner hires a professional baseball player known for hitting home runs to hit ten balls with each bat and he measures the distance each ball is hit to test the company's claim. The results of the batting experiment are shown in the following table. Construct a 90 % confidence interval for the true difference between the mean distance hit with the new model and the mean distance hit with the older model. Assume that the variances of the two populations are the same. Let Population 1 be the distances of balls hit with the new model baseball bat and Population 2 be the distances of balls hit with the old model. Round the endpoints of the interval to one decimal place, if necessary. Hitting Distance (in Feet) New Model Old Model 215 234 202 298 224 294 211 246 215 268 248 211 255 226 228 284 247 221 214 259
