In a test of hypothesis, the null hypothesis is that the population proportion is equal to 0.68, and the alternative hypothesis is that the population proportion is less than 0.68. Suppose we make the test at the 10% significance level. A sample of size 255 produced a sample proportion of 0.72. What is the approximate p-value for this test? c. 0.7200 d. 0.9992 a. 0.9226 b. 1.0000 e. 0.5355
