Question

You are conducting a study to see if the probability of catching the flu this year is significantly less than 0.24. Thus you are performing a left-tailed test. Your sample data produce the test statistic z=−2.554. Find the p-value accurate to 4 decimal places.

Since you are given the test statistic, you would need to find the probability corresponding to the appropriate region using normalcdf.

p-value =
