Type the correct answer in the box. use numerals instead of words. if necessary, use / for the fraction bar. an experiment is set up to study the weights of 35 mice after they are injected with a drug. the population mean is 23.50 grams with a standard deviation of 3.40 grams. the standard error of the sample mean is . (round off your answer to the nearest hundredth.)

The standard error of the sample mean is 0.57.

Step-by-step explanation:

It is given that the experiment is set up to study the weights of 35 mice after they are injected with a drug. The population mean is 23.50 grams with a standard deviation of 3.40 grams.

The formula for standard error of the sample mean is

Therefore the standard error of the sample mean is 0.57.

if this is really you s much. i only have 3 points left and i have 2 questions to ask

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl
