A manufacturer of chocolate chips would like to know whether its bag filling machine works correctly at the 420 gram setting. It is believed that the machine is underfilling the bags. A 49 bag sample had a mean of 413 grams. Assume the population variance is known to be 676 . A level of significance of 0.1 will be used. Find the P-value of the test statistic. You may write the P-value as a range using interval notation, or as a decimal value rounded to four decimal places.

The  value is  

Step-by-step explanation:

From the question we are told that

   The population mean is  

   The The  sample  size is

    The sample  mean is  

    The  population variance is  

Generally the population standard deviation is  mathematically represented as

The null hypothesis is  

The  alternative  hypothesis is

 Generally the test statistics is mathematically represented as

=>        

=>      

The  p-value is  obtained from the z-table table and the value is  

i think it is c, not positive though
