The owner of the House of Greens Greenhouse wants to estimate the mean height that her seedlings grow. A sample of 18 plants were chosen and their growth was recorded over a period of a month. It was found that the sample mean was 18.00 cm and the sample standard deviation was 3.49 cm. Given this information, develop a 95.0% confidence interval estimate for the population mean (assuming the best point estimate for the population mean is the sample mean). g

step-by-step explanation:

d is the correct answer

step-by-step explanation:

x= 8 because 3x = 3 * 8, and 3*8 = 24

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
