Answer:
The standard deviation of the sampling distribution of sample means would be 0.8186.
Step-by-step explanation:
We are given that
Mean of population=23.2 pounds
Standard deviation of population=6.6 pounds
n=65
We have to find the standard deviation of the sampling distribution of sample means.
We know that standard deviation of the sampling distribution of sample means
=
Using the formula
The standard deviation of the sampling distribution of sample means
=

Hence, the standard deviation of the sampling distribution of sample means would be 0.8186.
Answer:
The runners drank 661 bottles of water.
Step-by-step explanation:
Subtract 661 from 750, and you are left with 89.
I think it is $900 because .15* 6000 is 900. This means Victoria needs to pay $900. <span />
