You wish to test the following claim (HaHa) at a significance level of =0.02=0.02. Ho:=80.9Ho:=80.9 Ha:<80.9Ha:<80.9 You believe the population is normally distributed, but you do not know the standard deviation. You obtain a sample of size n=74n=74 with mean M=77M=77 and a standard deviation of SD=8.4SD=8.4. What is the test statistic for this sample? (Report answer accurate to three decimal places.) test statistic = 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)
  • greater than

This test statistic 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 80.9.
  • There is not sufficient evidence to warrant rejection of the claim that the population mean is less than 80.9.
  • The sample data support the claim that the population mean is less than 80.9.
  • There is not sufficient sample evidence to support the claim that the population mean is less than 80.9.
