Is this the cas 4074 0-20.256 22, 16,708 0.004 106 17899 / / 109.567 22202,22414 331.000 wing table shows how annual household VMT (vehicle miles traveled) varies on density. As you can see, as population density increases, annual VMT cases. Is this the case if you compare the population density subgroups D and E? ct a two-tailed test at the 5% significance level, and write your conclusion. Is the rence statistically significant?

Answer 1

The hypothesis being tested is:

H₀: µ₁ = µ₂

H₁: µ₁ ≠ µ₂

D	E
21723	20256
17070	16708
17175	23793
Standard error	169.406
The test statistic, z	8.65967
p-value	1

The p-value is 1.0000.

Since the p-value (1.0000) is greater than the significance level (0.05), we cannot reject the null hypothesis.

Therefore, we cannot conclude that there is a difference statistically significant.
