Is this an exam? looks like it
Answer:
98% confidence interval is (-0.105 , 0.265)
Step-by-step explanation:
n1 = 75 n2 = 75
X1 = 48 X2 = 42
P1 = X1/N1 = 0.64 P2 = X2/N2 = 0.56
98% confidence interval for difference between two proportions is :
P1 - P2 <u>+</u> Z 
= 0.08 <u>+</u> 0.185
= (-0.105 , 0.265)
98% confidence interval is (-0.105 , 0.265)
<h2>
Answer with explanation:</h2>
A. For males, Third quartile =14, First quartile = 3 (approx)
IQR = Third quartile - First quartile
= 14-3 = 11
B. For males, Median = 12
For females, Median = 17
The difference between the median values = 17-12=5
C. The mean would be a better measure of center for females because the data has no outliers.
The median would be a better measure of center for males because the data has outliers.
D. Reason for outlier: A large number of males gone for movie which is extreme value for the remaining values.
Let's calculate all expenses per month
a) Mortgage $1,255 →→→→→→→→→ = $1,255 per month
b)Taxes $2,881 per year →→ $2,881/12 = $240.083 per month
c) insurance $156 →→→→→→→→→→ =$156 per month
d) HOA fees $320 per year→→→=$320/12 = $ 26.66 per month
e)utilities $475→→→→→→→→→→→→→=$475
Average monthly expenditure: a) + b) + c) + d) = $2,152.75
I need a second equation to solve this, something like x + y = 12 or something
