Suppose are running a study/poll about the probability of a true negative on a test for a certain cancer. You randomly sample 140 people and find that 52 of them match the condition you are testing.


Suppose you are have the following null and alternative hypotheses for a test you are running:


H₀:p=0.42H₀:p=0.42
H_a:p<>_a:p<>


Calculate the test statistic, rounded to 3 decimal places
