Question
1. You are going to test a hypothesis concerning the difference between two population means. One of the steps to do this is to find the standard error. Suppose you have two samples with 50 observations each and standard deviations of 74.1 and 62.7. What is the standard error? Answer to two decimal places.
2. You are going to test a hypothesis concerning the difference between two population means. One of the steps to do this is to find the standard error. Suppose you have two samples with 40 observations each and standard deviations of 73.4 and 102.1. What is the standard error? Answer to two decimal places.
Explanation / Answer
Answer:- Standard error= [(74.1)2/50 +(62.7)2/50] =[(109.82 +78.63)]= 13.73
Answer:- Standard error= [(73.4)2/40 +(102.1)2/40] =[(134.69 +260.61)]= 19.88
