You wish to test the following claim (Ha) at a significance level of α=0.05.


      Ho:μ=63.9
      Ha:μ<>


You believe the population is normally distributed, but you do not know the standard deviation. You obtain a sample of size n=24 with mean M=51 and a standard deviation of SD=16.6.


What is the p-value for this sample? (Report answer accurate to four decimal places.)
p-value =


The p-value is...




  • less than (or equal to) αα

  • greater than αα







This p-value leads to a decision to...




  • reject the null

  • accept the null

  • fail to reject the null







As such, the final conclusion is that...




  • There is sufficient evidence to warrant rejection of the claim that the population mean is less than 63.9.

  • There is not sufficient evidence to warrant rejection of the claim that the population mean is less than 63.9.

  • The sample data support the claim that the population mean is less than 63.9.

  • There is not sufficient sample evidence to support the claim that the population mean is less than 63.9.
