The British Medical Journal prints short and readable versions of articles along with longer versions available online. The journal asked a random sample of 100 of its recent authors, "Should the journal continue using this system?" In the sample, 72 said "yes." Do the data give good evidence that more than two-thirds (67%) of authors support continuing this system?  

To explore the suspicion above, conduct a significance test at level 0.05 using the hypotheses:

H0 : p = 0.67

 

Ha : p Blank #1    0.67

 

Blank #1: Determine the correct alternative hypothesis by filling in the blank with <, > or not equals.

Blank #2: Report the test statistic to two decimal places

Blank #3: Report the p-value to four decimal places

Blank #4: Give the test decision: (reject or do not reject) H0

 

Blank #5: Evidence _______________(favors or does not favor) that more than 67% of authors support continuing the system

Blank #6: Is this result borderline? In other words, if you changed the decision level to another usual level such as 0.01 or 0.10, would it change the decision you made here? (yes or no)
