Use the normal distribution and the given sample results to complete the test of the given hypotheses. Assume the results come from a random sample and use a 5% significance level. Test Ho : p = 0.2 vs Ha : p # 0.2 using the sample results p = 0.26 with n = 997 Round your answer for the test statistic to two decimal places, and your answer for the p-value to three decimal places. test statistic = i %3D p-value = i Conclusion: * Họ.

use the t- distribution and the sample results to complete the test of the hypothesis. use a 5% significance level. Assume the results come from a random sample , and if the sample size is small, assume the underlying distribution is relatively normal .  H0: miu=4 vs Ha: miu not equal to 4 using the sample results x bar =4.8 s= 2.3 with n=15.   WHAT IS THE P-VALUE?
