Answer:
3/10
Step-by-step explanation:
Subtract the sum of 1/3, 4/15 and 1/10 from 1:
10/30 + 8/30 + 3/30 = 21/30, or 7/10
Then: 1 - 7/10 = 3/10
To do this, you can just multiply across. 3 times 1 equals 3 so your numerator is 3. 2 times 4 equals 8. Then, your answer would be 3/8. Hope this helps :)
Answer:
The true mean 
it probably could be larger, smaller, or equal to 22
Step-by-step explanation:
False.
By definition the sample mean is defined as:
For this case the value for the sample size is n =190 and the calculated sample mean is 
. This value represent the sample and for this case we can't assume that this value represent at all the population as the population mean since we probably have variability from the data of the students at City College.
So we can conclude that the true mean it probably could be larger, smaller, or equal to 22
