You are performing a left-tailed test with test statistic $z=-0.67$, find the $\mathrm{p}$-value to 4 decimal places
Rounding to 4 decimal places, the final answer is \(\boxed{0.2514}\).
Step 1 :We are given a left-tailed test with test statistic \(z=-0.67\).
Step 2 :The p-value in a left-tailed test is the probability that a random variable is less than the test statistic.
Step 3 :In this case, we need to find the probability that a standard normal random variable is less than -0.67.
Step 4 :We can use the cumulative distribution function (CDF) of the standard normal distribution to find this probability.
Step 5 :The CDF at a point x gives the probability that a standard normal random variable is less than or equal to x.
Step 6 :Using the CDF, we find that the p-value is approximately 0.25142889509531013.
Step 7 :Rounding to 4 decimal places, the final answer is \(\boxed{0.2514}\).
