Question
A sample of 36 observations is selected from a normal population. The sample mean is 49, and the population standard deviation is 5. Conduct the following test of hypothesis using the 0.05 significance level. He: H=50 H₁: p 50 a. Is this a one- or two-tailed test? O One-tailed test OTwo-tailed test b. What is the decision rule? Check O Reject Ho if -1.96 < z < 1.96 Reject He if z<-1.96 or z> 1.96

e-1. What is the p-value? (Round your z value to 2 decimal places and final answer to 4 decimal places.) p-value e-2. Interpret the p-value? (Round your z value to 2 decimal places and final answer to 2 decimal places.) There is a % chance of finding a z value this large by sampling error when HQ is true c. What is the value of the test statistic? (Negative amount should be indicated by a minus sign. Round your answer to 2 decimal places.) Value of the test statistic
