**Evaluating the Effectiveness of a Drug for Treating Insomnia in Older Adults: A Clinical Trial**A clinical trial was conducted to test the effectiveness of a drug for treating insomnia in older subjects. Here are the key observations from the study:- **Before treatment**: 23 subjects had a mean wake time of 105.0 minutes.- **After treatment**: The same 23 subjects had a mean wake time of 80.5 minutes and a standard deviation of 22.3 minutes.### ObjectiveAssume that the 23 sample values are from a normally distributed population. The goal is to construct a 95% confidence interval estimate of the mean wake time for a population with drug treatments. By doing so, we aim to answer the following questions:1. What does the result suggest about the mean wake time of 105.0 minutes before the treatment?2. Does the drug appear to be effective?### TaskConstruct the 95% confidence interval estimate of the mean wake time for a population with the treatment.### Confidence Interval CalculationYou are required to calculate the 95% confidence interval for the mean wake time (\( \mu \)) for the population after treatment.The form for entering your calculated confidence interval is as follows:\[ \text{min} < \mu < \text{min} \]*Note: Round your answer to one decimal place as needed.*### Entering Your AnswerPlease enter your lower and upper bounds of the confidence interval in the respective edit fields and then click "Check Answer".If you have any questions, feel free to seek help using the available resources.![Help Icon](https://www.example.com/help-icon.jpg)---By accurately constructing and interpreting the confidence interval, we can determine the effectiveness of the drug in reducing wake times in older adults suffering from insomnia.

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
