The  decision is to fail to reject the null hypothesis

This  means that  the population mean apartment rental rate now does not exceeds the level reported in 2002

Step-by-step explanation:

From the question we are told that

   The population mean is  

   The  population standard deviation is  

   The sample  size is  

   The sample mean is  

    The sample standard deviation is

   The  level of significance is

The null hypothesis is  

The  alternative hypothesis is  

   The test statistics is evaluated as

=>      

=>      

So from  z-table  the p-value is obtained, the value is  

So From the value obtained we see that

        so  we  fail to reject the null hypothesis

by definition, an arc subtended by a central angle of some given measure has the same measure. so .
