Multiply her pay per hour times number of hours worked.

For a normal 40 hour week, she is paid 16.34 per hour:

16.34 x 40 = 653.60


Overtime is any  hours over 40, so if she works 60 hours, she would have 20 hours of over time.

Multiply 20 hours by her overtime rate:

20 x 24.51 = 490.20

Now add this to her normal 40 hour pay:

490.20 + 653.60 = 1143.80


So her range is from 40 hours: 653.60 to 60 hours: 1143.80


The answer would be A

Complete Question

The complete question is shown on the first uploaded image

Answer:

the null hypothesis is  H_o  :  \mu =  122

the alternative hypothesis is H_a  :  \mu \ne  122

The test statistics is  t =  - 1.761

The p-value is  p =  P(Z  <  t ) = 0.039119

so

    p  \ge 0.01

Step-by-step explanation:

From the question we are told that

   The population mean is  \mu  = 122

     The sample size is  n=  38

    The sample mean is  \= x  =  116 \ feet

     The standard deviation is \sigma  =  21

     

Generally the null hypothesis is  H_o  :  \mu =  122

                the alternative hypothesis is H_a  :  \mu \ne  122

Generally the test statistics is mathematically evaluated as

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

substituting values

         t =  \frac { 116 -  122 }{\frac{ 21 }{ \sqrt{ 38} } }

         t =  - 1.761

The p-value is mathematically represented as

      p =  P(Z  <  t )

From the z- table  

     p =  P(Z  <  t ) = 0.039119

So  

     p  \ge 0.01
