**Constructing a Confidence Interval for a Population Mean**You measure 32 textbooks' weights and find they have a mean weight of 52 ounces. Assume the population standard deviation is 10.7 ounces. Based on this, construct a 95% confidence interval for the true population mean textbook weight.Give your answers as decimals, rounded to two decimal places.**[Input box]** < µ < **[Input box]**---To solve this, use the formula for the confidence interval for a population mean when the population standard deviation is known:\[\text{Confidence Interval} = \bar{x} \pm Z \left(\frac{\sigma}{\sqrt{n}}\right)\]Where:- $\bar{x}$ = sample mean = 52 ounces- $Z$ = Z-score corresponding to the desired confidence level (for 95%, $Z \approx 1.96$)- $\sigma$ = population standard deviation = 10.7 ounces- $n$ = sample size = 32Calculate the margin of error and then determine the interval.

statistics practitioner took a random sample of 48 observations from a population whose standard deviation is 23 and computed the sample mean to be 100. 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. A. Estimate the population mean with 95% confidence. Confidence Interval = B. Estimate the population mean with 95% confidence, changing the population standard deviation to 47; Confidence Interval = C.

Construct the confidence interval for the population mean. If the sample size is 35, the sample mean is 4.8, and the sample standard deviation is 2.2. We also know that the population standard deviation is 2.6. Use the Confidence Level = 95%. Use parentheses and four decimal places.
Determine whether the statement below makes sense or does not make sense. Explain clearly. Based on our sample, the 95% confidence interval for the mean amount of television watched by adults in a nation is 3.5 to 4.1 hours per day. Therefore, there is 95% chance that the mean for all adults in the nation will fall somewhere in this range and a 5% chance that it will not. Choose the correct answer below. O A. The statement makes sense. There is 95% probability that the confidence interval limits actually contain the true value of the population mean, so the probability it does not fall in this range is 100% - 95% = 5%. O B. The statement does not make sense. The probability the population mean is greater than the upper limit is 5% and the probability it is less than the lower limit is 5%, so the probability it does not is 5% + 5% = 10%. O C. The statement makes sense. There is 5% probability that the confidence interval limits do not contain the true value of the sample mean, so the…
