Aurora is conducting a one-sample ? test of the null hypothesis ?0:?=0.14H0:p=0.14 against the alternative ??:?<0.14Ha:p<0.14, where ?p is the population proportion. She requires her results to be statistically significant at a level of ?=0.01α=0.01. She selects a random sample of size ?n = 300 and calculates the sample proportion, ?̂ = 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.
