Dullco Manufacturing claims that its alkaline batteries last at least 40 hours on average in a certain type of portable CD playe
algol13

Answer:

The value is  p- value  = 0.041815

Step-by-step explanation:

From the question we are told that

  The  population mean is \mu  =  40 \ hours

  The  sample size is  n  =  18

    The  sample mean is  \= x =  37.8 \ hours

   The standard deviation is  \sigma  = 5.4\ hours

The null hypothesis is  H_o  :  \mu =  \ge 40

The alternative hypothesis is  H_a  :  \mu < 40 \ hour s

Generally the test statistic is mathematically evaluated as

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

      t=  \frac{37.8 - 40}{ \frac{5.4}{ \sqrt{18 } }

      t=  -1.73

From the z - table the p-value is obtained and the value is  

      p- value  =  P(Z <  -1.73)

        p- value  = 0.041815
