Question

Given the two independent samples below, conduct a hypothesis test for the desired scenario. Assume all populations are approximately normally distributed.

Sample 1 Sample 2
 n1=n1= 124  n2=n2= 164
 ¯x1=x¯1= 27  ¯x2=x¯2= 23.1
s1=s1= 3.6 s2=s2= 4.1

 

Test the claim:

Given the null and alternative hypotheses below, conduct a hypothesis test for α=0.1α=0.1.

H0H0: μ1=μ2
HaHa: μ1>μ2

  1. Given the alternative hypothesis, the test is 
        
  2. Determine the test statistic. Round to four decimal places.
    t=

  3. Find the pp-value. Round to 4 decimals.
    pp-value = 

  4. Make a decision.
    • Fail to reject the null hypothesis.
    • Reject the null hypothesis.
