Answer:
And we can find this probability with this difference and using the normal standard table:
Then the answer would be approximately 55.3% of women between the specifications. And that represent more than the half of women
Step-by-step explanation:
Let X the random variable that represent the weights of a population, and for this case we know the distribution for X is given by:
Where
and
We are interested on this probability
And the best way to solve this problem is using the normal standard distribution and the z score given by:
If we apply this formula to our probability we got this:
And we can find this probability with this difference and using the normal standard table:
Then the answer would be approximately 55.3% of women between the specifications. And that represent more than the half of women
Answer:
20
Step-by-step explanation:
The pattern goes
+3, +4, +5, +6, +7...
14+6=20
The missing number is 20
<span>(1) What are the values of the sample proportion of people who live within 1 mile of a hazardous waste site and its standard error?
Solution:
pˆ = 0.3, and standard error p
0.3 Ă— 0.7/450 = 0.0216.
(2) What are the values of the sample proportion of people who live outside of the 1 mile radius around a hazardous waste site and its standard error?
Solution:
pˆ = 0.7, and standard error p
0.3 Ă— 0.7/450 = 0.0216.</span>
