Question

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

      Ho:μ=56.3
      Ha:μ<56.3

You believe the population is normally distributed, but you do not know the standard deviation. You obtain a sample of size n=21n=21 with mean M=55 and a standard deviation of SD=5.4

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 56.3.
  • There is not sufficient evidence to warrant rejection of the claim that the population mean is less than 56.3.
  • The sample data support the claim that the population mean is less than 56.3.
  • There is not sufficient sample evidence to support the claim that the population mean is less than 56.3.
