So, if tom eats 10 bananas in 10 days
than, monkey have eaten 40 apples and 20 bananas
hope this helped
38- b/c they are supplementary so 180-142=38
Answer:
a)
The 95% confidence interval would be given by (0.799;0.847)
b)
And rounded up we have that n=622
c)
And rounded up we have that n=1068
Step-by-step explanation:
Part a

In order to find the critical value we need to take in count that we are finding the interval for a proportion, so on this case we need to use the z distribution. Since our interval is at 95% of confidence, our significance level would be given by
and
. And the critical value would be given by:
The confidence interval for the mean is given by the following formula:
If we replace the values obtained we got:
The 95% confidence interval would be given by (0.799;0.847)
Part b
The margin of error for the proportion interval is given by this formula:
(a)
And on this case we have that
and we are interested in order to find the value of n, if we solve n from equation (a) we got:
(b)
And replacing into equation (b) the values from part a we got:
And rounded up we have that n=622
Part c
And rounded up we have that n=1068
If we change everything to the same denominator it will look like this. 24/30 and he wants to take 10/30. 24/30 - 10/30 is 14/30 so 14/30 - 10/30 is 4/30. *He can take 2 1/3 pieces*
