Estimation

A new framework of data analysis where the new statistical methods are used for interpreting the results and analyzing the data is known as estimation in statistics.

2.1
2.9
2
2.8
2.7
2.7
2.5
2.3
What is a point estimate for the population mean length of time. (Round answer to 2 decimal places)
What must be true in order to construct a confidence interval in this situation?
V Select an answer
The sample size must be greater than 30
ean length of time. (Round the critical value to 3 decimal
s.)
The population must be approximately normal
The population standard deviation must be known
The population mean must be known
What does it mean to be "99% confident" in this problem?
99% of all times will fall within this interval.
The confidence interval contains 99% of all sample times.
99% of all confidence intervals found using this same sampling technique will contain the population mean
time.
There is a 99% chance that the confidence interval contains the sample mean time.
Suppose that the company releases a statement that the mean time for all patients is 2 hours.
Is this possible? ?

A political newspaper, Politically Sound, is interested in the distances voters in Rising Falls County live from their nearest polling station. Politically Sound has hired you to estimate the population mean of all such distances for voters in this county. To estimate this population mean, you select a random sample of 17 Rising Falls County voters and record the distance (in km) each voter lives from their nearest polling station. Assume the population is approximately normally distributed. Based on your sample, follow the steps below to construct a 99% confidence interval for the population mean of all the distances voters in Rising Falls County live from their nearest polling station.
