Question
Suppose we want to test the null hypothesis H0 : p = 0.34 against the alternative hypothesis H1 : p > 0.34. Suppose also that we observed 120 successes in a random sample of 300 subjects and the level of significance is 0.05. What is the critical value for this test? Question 3Select one:a.-1.6449b.1.96c.1.2816d.1.6449
Solution
The critical value for this test can be found by looking up the z-score in a standard normal distribution table that corresponds to the given level of significance. Since the alternative hypothesis is p > 0.34, we are conducting a one-tailed test.
The level of significance is 0.05. For a one-tailed test, we use this value directly (we don't need to divide it by 2 as we would for a two-tailed test).
Looking up 0.05 in the z-table, we find a z-score of 1.6449.
So, the correct answer is d. 1.6449.
