Answer:
The null hypothesis is [tex]H_o : \mu = 16[/tex]
Step-by-step explanation:
From the question we are told that
The standard deviation is [tex]\sigma = 0.2 \ ounce[/tex]
The sample size is n = 15
The population size is N = 500
The sample mean is [tex]\= x = 11.75 \ ounce[/tex]
The population mean is [tex]\mu = 16\ ounce[/tex]
From the question we are told the confidence level is 95% , hence the level of significance is
[tex]\alpha = (100 - 95 ) \%[/tex]
=> [tex]\alpha = 0.05[/tex]
Generally the null hypothesis is [tex]H_o : \mu = 16[/tex]
