Answer:
The standard deviation of the sample mean is 16.98.
Explanation:
The standard deviation of the sample mean differences is given as by the difference of the 2 standard deviations.This is given as
Difference of standard deviations=21.2-17.6 = 3.6
Now the ratio of the difference to the largest standard difference is given as
Ratio=3.6/21.2=0.1698
Converting this into percentage as 0.1698x100=16.98
The standard deviation of the sample mean is 16.98.

Dear grandchild or great grandchild or what so ever,
How's life? Can people now teleport? xD
I bet technology improved at your time. The technology here is well too. We talk on phones and all. We walk run or use transport. We live in houses,apartments etc. We socialize and meet people whether personally or online. I wish a teleportation device would be invented so i can finish work in other places faster. I wonder if i'll still be alive if its invented.
warm regards,
old relative
The correct answer should be the following one - <span>the coastal region along the Southeast African border, which had port facilities to support trade.
This is the geographical factor that attracted traders of east Africa to this location, which in turn led to the creation of the Swahili culture. Swahili refers to the culture of the Bantu people in Africa, in countries such as Tanzania, Uganda, Mozambique, etc.
