Find the p-value for the indicated hypothesis test with the given standardized t

Question

Find the p-value for the indicated hypothesis test with the given standardized test statistics, z. Decide whether to Ho for the given level of significance a. Two tailed test with test statistic z= -2.11 and a=0.04 P value = ____ ( round to four decimal places as needed) Find the p-value for the indicated hypothesis test with the given standardized test statistics, z. Decide whether to Ho for the given level of significance a. Two tailed test with test statistic z= -2.11 and a=0.04 P value = ____ ( round to four decimal places as needed) Two tailed test with test statistic z= -2.11 and a=0.04 P value = ____ ( round to four decimal places as needed)

Explanation / Answer

SOl)

Z cal = -2.11 and alpha=0.04

Now p value= 2* P(Z<-2.11)

= 2*(0.5 -P(-2.11<Z<0))

= 2*(0.5 - 0.4826)

= 2*(0.0174)

P value = 0.0348
