Question

Use the information given below to find the P-value. Also, use a 0.05 significance level and state the conclusion about the null hypothesis (reject the null hypothesis or fail to reject the null hypothesis). The test statistic in a left-tailed test is z= - 1.29. What is the P-value? P-value = (Round to four decimal places as needed.)

Answer 1

Solution- * iven, Z = -1.29 - 1.29, a left tailed test. p.value PLZ <-1.29) 0.0985 Since, p-value is gaeater than alpha 0.05 : fail to Reject the null hypothesis. * The nell and alternative hypothesis colo Hoip = 0.25 Null hypothesd US Hai Pt 0.25 C... Alternative hypothesis Hese, u= 440, x= 100 / P 100 440 0.2213 л The test Statistic is ph-P z = 0.2273 - 0.25 P(1-P) 0.25 (+-0.25) 440 = -1.10
