Answer:
And rounded up we have that n=1068
Step-by-step explanation:
For this case we have the following info given:
the margin of error desired
the level of confidence given
The margin of error for the proportion interval is given by this formula:
(a)
the critical value for 95% of confidence is 
We can use as estimator for the population of interest
. 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=1068
22:6 is one of them. Do you need more than one?
Answer:
the top one
because identity of addition is adding 0
Answer:
There is an association because the relative frequencies by row are different.
Step-by-step explanation:
The relative frequencies by row are:
90 perfect t-shirts out of 90+6=96 t-shirts is:
90/96 = 0.9375
6 flawed t-shirts out of 96 t-shirts is:
6/96 = 0.0625
40 perfect sweatshirts out of 40+10=50 sweatshirts is:
40/50 = 0.8
10 flawed sweatshirts out of 50 sweatshirts is:
10/50 = 0.2
The relative frequencies by row are different; this means there is an association.

➷ Hank charges $75 for a visit plus $45 per hour.
Therefore, for an hour, Hank would charge $120 as 75 + 45 = 120
Mr Fixit:
As it is for one hour, we look at the first function because the time is 'less than or equal to an hour'.
Mr Fixit would charge $95 for an hour.
Therefore, Hank charges $25 more than Mr Fixit.
