Answer:
c. Ha: µ1 – µ2 ˃ 10
Step-by-step explanation:
given that a researcher is interested in determining whether the mean of group 1 is 10 units larger than the mean of group 2.
There are two groups with different means.
We want to check whether the difference of mean 1 - mean 2 is greater than 10 units
For this we set up hypotheses with null as difference equal to 10 and alternate as difference large than 10
Hence the hypotheses would be
H0: Mean 1 - Mean 2 =10
Ha: Mean 1 -Mean 2 >10
In notations this would be
c. Ha: µ1 – µ2 ˃ 10
