Reynaldo is conducting a one-sample z-test of the null hypothesis Ho : 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 a = 0.01. He selects a random sample of size n = 150 and calculates the sample proportion, = 0.78. What is the value of the standardized test statistic? (Round to 2 decimal places)
