The researcher has limited resources. he sends 9 emails from a latino name, and 14 emails from a non-latino name. for the latino names, the mean response time was 421 minutes (standard deviation of 82 minutes). for the non-latino names, it was 366 minutes (standard deviation of 101 minutes). calculate the standard error for the difference in means.

38.41 minutes

Step-by-step explanation:

The standard error for the difference in means is given by :-

where , = Standard deviation for sample 1.

= Size of sample 1.

= Standard deviation for sample 2.

= Size of sample 2.

Let the sample of Latino name is first and non -Latino is second.

As per given , we have

The standard error for the difference in means will be :

Hence, the standard error for the difference in means =38.41 minutes

i think it is 70

step-by-step explanation:

your answer would be 12
