Answer:
The sample mean is 13.
The sample variance is 0.2286.
The sample standard deviation is 0.4781.
Step-by-step explanation:
The sample is:
S = {12.6, 12.9, 13.4, 12.3, 13.6, 13.5, 12.6, 13.1}
The sample is of size <em>n</em> = 8.
The formula to compute the sample mean, sample variance and sample standard deviation are:
Compute the sample mean as follows:
The sample mean is 13.
Compute the sample variance as follows:
The sample variance is 0.2286.
Compute the sample standard deviation as follows:
The sample standard deviation is 0.4781.
