The housing market has recovered slowly from the economic crisis of 2008.​ Recently, in one large​ community, realtors randomly
Gwar [14]

Answer:

Step-by-step explanation:

Given that the housing market has recovered slowly from the economic crisis of 2008.​ Recently, in one large​ community, realtors randomly sampled 38 bids from potential buyers to estimate the average loss in home value.

s = sample std deviation = 3000

Sample mean = 9379

Sample size n = 38

df = 37

Std error of sample mean = \frac{s}{\sqrt{n} } \\=486.66

confidence interval 95% = Mean ± t critical * std error

=Mean ±1.687*486.66 = Mean ±821.003

=(8557.997, 10200.003)

a) If std deviation changes to 9000 instead of 3000, margin of error becomes 3 times

Hence 2463.008

b) The more the std deviation the more the width of confidence interval.

Solve the system using substitution . y =2x +4 , 2x - y = 6
babymother [125]

no solution

substitute y = 2x + 4 into the other equation

2x - (2x + 4) = 6 ( distribute and simplify )

2x - 2x - 4 = 6 ( add 4 to both sides )

0 = 10 ← not possible

Hence the system has no solution
