Suppose we want to test Ho: p = 0.40 vs. Ha: p # 0.40 using a sample proportion of 420 out of 1000. You are going to compute the p-value for this scenario 2 different ways, and then set up a confidence interval for p in this question.[2 pts] Find the p-yalue using a randomization distribution in StatKey {like you would have done in Chapter 4). PS if you get a randomization distribution that turns all red or shows no red, you may have forgotten to tell StatKey what the null value is. The default null proportion in StatKey is 0.5, but this question is not about a null proportion of 0.50. g. [4 pts] Now, nd the p-value using the theoretical normal distribution. This is different from using the randomization distribution in part b. You will need to either use the theoretical normal distribution in StatKey or the table of standard normal probabilities and use them as explained in the Week 13 {Section 5.1 and 5.2 content folder. In addition to reporting your p-value, sketch a graph of the standard normal distribution and shade the area that you are finding below. {And remember to clearly indicate the area/p-value}. h. [2 pts] Compare the two p-values found in part g and in part b. What do you notice? Are the two p-values similar, exact, or very different? Why do you thinkthat could be
