1. -1, 2,8,11
plug the values into the equation and solve
Answer:
The p-value is 0.0229
Step-by-step explanation:
With 
we have an upper-tail alternative. Because the p-value is defined as the probability of getting a value at least as extreme as the value observed. The observed value is given by the test statistic z = 1.997 which comes from a standard normal distribution. Therefore, we compute the p-value in the following way P(Z > 1.997) = 0.0229, i.e., the p-value is 0.0229
