Question

You wish to test the following at a significance level of α=0.05α=0.05.

      H0:p=0.41H0:p=0.41
      H1:p>0.41H1:p>0.41

You obtain a sample of size n=567n=567 in which there are 257 successful observations.

For this test, we use the normal distribution as an approximation for the binomial distribution.

For this sample...

  1. The test statistic (zz) for the data =  (Please show your answer to three decimal places.)
  2. The p-value for the sample =  (Please show your answer to four decimal places.)
  3. The p-value is...
    • greater than αα
    • less than (or equal to) αα
  4. (Recall that when p(-value) is low, the null must go; when p(-value) is high, the null must fly)
    Base on this, we should ....
    • accept the null hypothesis
    • reject the null hypothesis
    • fail to reject the null hypothesis
  5. As such, the final conclusion is that...
    • The sample data suggest that the population proportion is significantly greater than 0.41 at the significant level of αα = 0.05.
    • The sample data suggest that the population proportion is not significantly greater than 0.41 at the significant level of αα = 0.05
