For a population, N=16,000 and p=0.19 . Find the z value for p^=0.26 for n=60 .
z = - p / sqrt( p ( 1 - p) / n)
= 0.26 - 0.19 / sqrt( 0.19 * 0.81 / 60)
= 1.38
z = 1.38

Consider the following hypotheses. Ho: Ps 0.19 H:p> 0.19 Given that p = 0.2, n= 130, and a = 0.01, answer the following questions. a. What conclusion should be drawn? b. Determine the p-value for this test. vral conclusion should be diawn? Reject Ho. There is insufficient evidence that p > 0.19. Do not reject Ho. There is insufficient evidence that p>0.19. c. Do not reject Ho. There is sufficient evidence that p>0.19. D. Reject Ho. There is sufficient evidence...
Find the critical value z Subscript alpha divided by 2 that corresponds to alpha = 0.19.
So, converted to a z interval, we wish to find P(0.26 < z < 0.79). Recall that since the z value is between two different values, we will need to subtract the table areas for Z, = 0.26 from the table area for z, = 0.79. Use this table to determine P(Z < 0.26) and P(Z < 0.79). Substitute these values into the formula to find the probability. (Round your answer to three decimal places.) P(0.26 < z < 0.79)...
