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.

Question

a. Determine the sampling distribution of the sample mean for samples of size 3. Interpret your answer in terms of the distribution of all possible sample mean brain weights for samples of three men.

The mean of the sample mean is

μx=1.401.40kg.

(Type an integer or a decimal. Do not round.)

The standard deviation of the sample mean is

σx=0.06350.063kg.

(Round to four decimal places as needed.)

Interpret these answers in context.

For samples of three men, the individual brain weights have a normal distribution with a mean of

1.41.4 kg and a standard deviation of 0.06350.0635 kg.

(Type integers or decimals rounded to four decimal places as needed.)

Definition Definition Number of subjects or observations included in a study. A large sample size typically provides more reliable results and better representation of the population. As sample size and width of confidence interval are inversely related, if the sample size is increased, the width of the confidence interval decreases.
