Women athletes at the university of colorado, boulder, have a long-term graduation rate of 67% (source: the chronicle of higher
Elodia [21]

 

The solution would be like this for this specific problem:

H0: p = p0, or <span>
H0: p ≥ p0, or 
H0: p ≤ p0 </span>

 

find the test statistic z = (pHat - p0) / sqrt(p0 * (1-p0) / n) 

 

where pHat = X / n 

 

The p-value of the test is the area under the normal curve that is in agreement with the alternate hypothesis. <span>
H1: p ≠ p0; p-value is the area in the tails greater than |z| 
H1: p < p0; p-value is the area to the left of z 
H1: p > p0; p-value is the area to the right of z </span>

 

Hypothesis equation:

 

H0: p ≥ 0.67 vs. H1: p < 0.67 

 

The test statistic is: <span>
z = ( 0.5526316 - 0.67 ) / ( √ ( 0.67 * (1 - 0.67 ) / 38 ) 
z = -1.538681 </span>

 

The p-value = P( Z < z ) <span>
= P( Z < -1.538681 ) 
<span>= 0.0619</span></span>
