Ho: p < 0.5; Hạ: p = 0.5 O Ho: p = 0.5; Hạ: p > 0.5 O Họ: p - 0.5; Hạ:p < 0.5 O Hg: p - 0.5; Hạ: p • 0.5 (b) What sampling distribution will you use? O The Student's t, since np < 5 and ng < 5. The standard normal, since np > 5 and ng > S. O The standard normal, since np < 5 and ng < 5. O The Student's t, since np > 5 and ng > 5. What is the value of the sample test statistic? (Round your answer to two decimal places.) -2.43324x (C) Find the P-value of the test statistic. (Round your answer to four decimal places.) 0.0068 Sketch the sampling distribution and show the area corresponding to the P-value. (d) Based on your answers in parts (a) to (c), will you reject or fail to reject the null hypothesis? Are the data statisticlly significant at k At the a - 0.01 level, we reject the null hypothesis and conclude the data are statistically significant. O At the a - 0.01 level, we reject the null hypothesis and conclude the data are not statistically significant. At the a- 0.01 level, we fail to reject the null hypothesis and conclude the data are statistically significant. • At the a- 0.01 level, we fail to reject the null hypothesis and conclude the data are not statistically significant.

When I checked it says the answer is not 18

what are the values of s1 and s2?

I have this question on my homework and I don't see a pattern. I have to explain how the trick works.  "Think of a number. Add 17. Double the result. Subtract 4. Double the result. Add 20. Divide by 4. Subtract 20. Your answer will be your original number."
