The director of a state agency believes that the average starting salary for clerical employees in the state is less than $30,00
ss7ja [257]

Answer:

The test statistics is   z = -1  

Step-by-step explanation:

From the question we are told that

   The sample size is  n  =  100

  The null hypothesis  is  H_o : \mu = \$30000

   The alternative hypothesis is  H_a  :  \mu  < \$ 30000

   The sample mean is  \= x  = \$29,750

    The standard deviation is  \sigma  = \$2,500

    The level of significance is  \alpha =0.05

Generally the test statistics is mathematically represented as

        z = \frac{\= x - \mu }{ \frac{ \sigma}{ \sqrt{n} } }

=>      z = \frac{29750 - 30000 }{ \frac{ 2500}{ \sqrt{100} } }

=>      z = -1
