Answer:
We can conclude that there is significant evidence that Northwood residents owned their homes for a longer period of time compare to residents in the Southlake area
Step-by-step explanation:
H0 : μ1 = μ2
H1 : μ1 < μ2
Given :
n1 = 14 ; n2 = 28
x1 = 7.4 ; x2 = 9.1
s1 = 2.3 ; s2 = 2.9
α = 0.05
Test statistic :
(x1-x2) ÷ sqrt[(((n1-1)*s1² + (n2-1)*s2²) ÷ df) * (1/n1+1/n2)]
(7.4 - 9.1) ÷ sqrt[(((13*2.3^2) + (27*2.9^2)) ÷ 40) * (1/14 + 1/28)]
t = -1.7 ÷ sqrt[((68.77 + 227.07) / 40) * 0.1071428]
t = -1.7 ÷ sqrt(0.7924281488)
t = - 1.7 ÷ 0.8901843
t = - 1.909
t = - 1.91
The Pvalue :
P(t < - 1.91) = 0.028067
At α = 0.05 ;
Pvalue < α ; We reject the Null
We can conclude that there is significant evidence that Northwood residents owned their homes for a longer period of time compare to residents in the Southlake area
Answer= 51
I plugged it into a calculator good luck
12 times 5 to the power of 7 divided by 2 is 468750

Step-by-step explanation:
Answer:
c: 5 x 3/5
Step-by-step explanation:
so the is 15 blocks shaded on the 25 grid
so i would work out each fraction answer and find which one makes 15/25
5 x 5/3 = 25/25
3/5 + 3/5 + 3/5 + 3/5 + 3/5 + 3/5 = 21/5
5 x 3/5 = 15/25
hope this helps :)
if the answer is wrong plz comment and i will fix thanks :)
