Answer:
The 90% confidence interval is 0.575 to 0.625.
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of 
, and a confidence interval 
, we have the following confidence interval of proportions.
In which
Z is the zscore that has a pvalue of 
.
For this problem, we have that:
90% confidence interval
So 
, z is the value of Z that has a pvalue of 
, so 
.
The lower limit of this interval is:
The upper limit of this interval is:
The 90% confidence interval is 0.575 to 0.625.
Answer:
D. $432.84
Step-by-step explanation:
The average daily balance is the weighted sum of the balances. The weight in each case is the number of days the account had that balance.
adb = (7×745.00 +10×585.15 +7×245.20 +7×90.75)/(7+10+7+7)
= 13,418.15/31
= 432.84
Nia's average daily balance was $432.84.
It means when the planes cross each other it is perpendicular to each other
==> 225 is 75% of 300 .
==> 225 is 25% smaller than 300 .
==> 225 is 3/4 of 300 .
==> 300 is 4/3 the size of 225 .
==> 300 is (33 and 1/3)% bigger than 225 .
==> 225 is 75 less than 300 .
==> 225 has 10 fewer factors than 300 has.
==> 300 has 2.25 times as many factors as 225 has.
==> 225 and 300 have 5 common factors.
==> The greatest common factor of 225 and 300 is 75 .
