9 , 5, 16, 14, 6
Calculate the mean
calculate the standard deviation (round to 3 decimals)
Homework Answers
Answer #1
Solution:
Given that,
9 , 5, 16, 14, 6
a)The mean of sample is 
x/n
= (9 + 5+ 16+ 14+ 6 / 5)
=10
The sample mean is
Sample standard deviation is s
s = 
1/(n-1)(x
-
)2
= 1/4
(9 - 10)2+ (5 - 10 )2+ (16 -10)2+ (14- 10 )2 +( 6 - 10 )2
=
23.5
= 4.8476798574163
The sample standard deviation is 4.848

The mean sugar content in breakfast cereal is manufactured to be
11g of sugar per serving- a serving is defined to be 30g of cereal.
the manufacturing process is controlled such that the standard
deviation is only 0.8 g per serving. after an overhaul of the
equipment, the sugar content is checked using a sample of 35
measurements which are averaged to find a mean sugar content of
10.7 g per serving. is there strong evidence that the true mean...

1) A sample of cereal boxes is randomly selected and the sugar
contents (grams of sugar per gram of cereal) are recorded. Those
amounts are summarized with these statistics: n = 16, ?̅ = 0.295g,
