Question 1115335
<font color="black" face="times" size="3">
p = population proportion of high school students that will attend college in the fall


Null Hypothesis: 
H0: p >= 0.75


Alternative Hypothesis: 
H1: p < 0.75


This is left-tailed test based on the inequality in the alternative hypothesis H1


Since this is a left tailed test, this means we will use the area under the curve to the left of the z-score 2.54


Using a <a href="http://davidmlane.com/hyperstat/z_table.html">calculator</a> or a <a href="http://www.z-table.com/">table</a>, you'll find that the area under the curve to the left of z = 2.54 is approximately 0.9945


The approximate P-value is 0.9945 which is larger than alpha = 0.05


So because <font color=blue>P-value > alpha</font>, this means we fail to reject the null hypothesis. In other words, we do not reject the null hypothesis.
