Reynaldo is conducting a one-sample z‑test of the null hypothesis H0:p=0.64 against the alternative Ha:p>0.64, where p is the population proportion. He requires his results to be statistically significant at a level of 1α=0.01. He selects a random sample of size n = 150 and calculates the sample proportion,  p^ = 0.78.  What is the value of the standardized test statistic?
