Answer:
The answer is A: Yes, all conditions have been met.
Random: Stated
Independent: None of the samples are greater then 10 percent of total population
Normal: n>30 so its assumed to be normal.
Sample sizes don't have to be the same unless it is a Matched pair test.
Explanation:
I fill like the reaction would be distillation or chromatography but distillation has to do with bioling points and chromatography has to do with how far the components separate along the material. but im in chemistry not advance placement.
Answer:
Kindly check explanation
Explanation:
Given that :
Mean height of women = 63.7 inches
Susan's height = 66 inches standard deviation = 1.75 inches
Number of standard deviations above or below the mean:
Zscore = (Susan's height - mean height) standard deviation
Zscore = (66 - 63.7) / 1.75
Zscore = 2.3 / 1.75
Zscore = 1.314
Meaning Susan's height is 1.314 standard deviations above the mean height of women.
To evaluate the average distance by which individual values vary from the mean. Use the relation:
[The value (X) - mean value (m)] / standard deviation
It is all based on opinion.
