7.43: Let
denote the random variable for height and
for the sample mean. Then if
is the mean of
So the probability that the difference between the sample and population means does not exceed 0.5 inch is

per the empirical or 68/95/99.7 rule.
7.44: For a sample of size <em>n</em>, the sample standard deviation would be
. We want to find <em>n</em> such that

Comparing to the equation from the previous part, this means we would need

so a sample of at least 157 men would be sufficient.

Answer:x=100
Step-by-step explanation:
Since you know that g(x)=3x-11 all you have to do is substitute that into g(x)=289. So you get 3x-11=289. To get x you have to add 11 on both sides.
3x-11=289
+11 +11
----------------
3x = 300
Divide 3 on both sides to get x by itself
3x =300
---- -------
3 3
x=100
Answer:
Your answer is C
Step-by-step explanation:
0.5 = Five tenths
and
0.05 = five hundredths
This is because 0.5 is like 50 cents and 0.05 is like 5 cents
The rest are wrong because A: 0.05 simply can't be bigger than 0.5
B is wrong because they aren't equal to each other
and D is wrong because 0.05 + 0.5 = 0.55
