**Description of the Educational Content:**A clinical trial was conducted to examine the effectiveness of a drug for treating insomnia in older subjects. The study involved 19 subjects. Before the treatment, these subjects had a mean wake time of 100.0 minutes. After the treatment, the mean wake time was reduced to 72.6 minutes, with a standard deviation of 22.8 minutes.**Objective:**To determine the effect of the drug treatment on mean wake time by constructing a 99% confidence interval for the mean wake time of a population with the treatment.**Instructions:**1. **Construct the 99% Confidence Interval:** - Calculate the interval estimate for the mean wake time for the population receiving the treatment. - Formula: \( \min < \mu < \min \) - Round the result to one decimal place as needed.2. **Analysis:** - If the confidence interval excludes the mean wake time of 100.0 minutes before the treatment, determine if there is a significant effect. - Consider whether the drug appears to be effective based on this confidence interval.3. **Answer Boxes:** - Fill in the confidence interval values and the conclusion on the drug's effectiveness. - The confidence interval [select option] the mean wake time of 100.0 min before the treatment, implying [select option] effect.**Conclusion:**- Analyze and input whether the drug treatment had a significant impact based on the confidence interval findings.

A clinical trial was conducted to test the effectiveness of a drug for treating insomnia in older subjects. Before treatment, 19 subjects had a mean wake time of 100.0 min. After treatment, the 19 subjects had a mean wake time of 72.6 min and a standard deviation of 22.8 min. Assume that the 19 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 100.0 min before the treatment? Does the drug appear to be effective?

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
