Question:

The sample mean foot length of a simple random sample of 25 third-graders is 22.5 cm. The standard error of the mean is 0.8 cm. Which one of the following is a correct interpretation for the standard error of the mean?

The typical distance between each individual foot length in the sample and the sample mean foot length is approximately 0.8 cm.

The typical distance between one sample mean foot length and another sample mean foot length is 0.8 cm.

The typical distance between each individual foot length in the population and the true mean foot length is approximately 0.8 cm.

The typical distance between means of samples of size 25 and the population mean foot length is approximately 0.8 cm

The typical distance between each individual foot length in the sample and the true mean foot length is approximately 0.8 cm.

The correct option is:

The typical distance between means of samples of size 25 and the population mean foot length is approximately 0.8 cm

Step-by-step explanation:

The standard error of the mean is a measure of the extent of variation of the mean in a sample of data from that of the value of the mean within the general population. It is a statistical measure of the probability that the size of a particular sample will approach that of the population mean, with reference to the principle of the central limit theorem.

Therefore, the interpretation of the standard error is that the variation between mean in a sample of 25 and that of the population is about 0.8 cm.

Answer from: Quest

a. turk and mcalister

b. howard, mission, and market

c. yes. since streets end some do not cross yet are not parallel to others. example: mcalister and 5th

step-by-step explanation:

parallel lines are lines which do not intersect ever and look a lot like railroad tracks. turk, mcalister and golden gate are examples of these.

intersect are streets which cross each other and a car on one can reach the other. howard, mission, and market intersect with 6th.

skew lines are lines which neither intersect nor are parallel. these lines exist here because some streets end and never intersect another like mcalister and 5th.

A. name the streets that are parallel to golden gate. b. name the streets that intersect 6th street.
