Aurora is conducting a one-sample z test of the null hypothesis H0:p=0.14 against the alternative Ha:p<0.14, where p is the population proportion. She requires her results to be statistically significant at a level of α=0.01. She selects a random sample of size n = 300 and calculates the sample proportion, p^ = 0.11. What is the value of the standardized test statistic and P-value of her test? Give z precise to two decimal places and the P-value precise to four decimal places.
