please help

You wish to test the following claim (HaHa) at a significance level of α=0.002α=0.002.

      Ho:μ=70.1
      Ha:μ>70.1

You believe the population is normally distributed and you know the standard deviation is 19.619.6. You obtain a sample mean of 77.377.3 for a sample of size 5454.

a) What is the test statistic for this sample? (Report answer accurate to three decimal places.) 
test statistic = 

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

c) The p-value is...

  • less than (or equal to) αα
  • greater than αα



d) This test statistic leads to a decision to...

  • reject the null
  • accept the null
  • fail to reject the null



e) As such, the final conclusion is that...

  • There is sufficient evidence to warrant rejection of the claim that the population mean is greater than 70.1.
  • There is not sufficient evidence to warrant rejection of the claim that the population mean is greater than 70.1.
  • The sample data support the claim that the population mean is greater than 70.1.
  • There is not sufficient sample evidence to support the claim that the population mean is greater than 70.1.
