1.

Null hypothesis HV0: Mean assessed values difference between buildings that are within one miles of the Freeway and those that are more than one mile from the Freeway is 0. That is

Alternative hypothesis HVa: Mean assessed values difference between buildings that are within one miles of the Freeway and those that are more than one mile from the Freeway is not 0. That is

Null hypothesis HA0: Mean age difference between buildings that are within one miles of the Freeway and those that are more than one mile from the Freeway is 0. That is

Alternative hypothesis HAa: Mean age difference between buildings that are within one miles of the Freeway and those that are more than one mile from the Freeway is not 0. That is

For 99% confidence interval (0.01 significance level), the critical Z values is 2.576

3.

P-value for the null hypothesis HV0 is 0.232 (Sig 2-tailed)

Since, p-value is greater than 0.01 significance level, we fail to reject null hypothesis HV0 and conclude that there is no strong evidence that mean assessed values difference between buildings that are within one miles of the Freeway and those that are more than one mile from the Freeway is not 0.

P-value for the null hypothesis HA0 is 0.337 (Sig 2-tailed)

Since, p-value is greater than 0.01 significance level, we fail to reject null hypothesis HV0 and conclude that there is no strong evidence that mean age difference between buildings that are within one miles of the Freeway and those that are more than one mile from the Freeway is not 0.
