Suppose Julio is a veterinarian who is doing research into the weight of domestic cats in his city. He collects information on 174 cats and finds the mean weight for cats in his sample is 10.75 lb with a standard deviation of 4.30 lb. What is the estimate of the standard error of the mean (SE)

The standard error of the mean (SE) is of 0.326lb.

Step-by-step explanation:

The standard error of the mean is given by the following formula:

In which s is the standard deviation of the sample and n is the size of the sample.

In this problem, we have that:

Then

The standard error of the mean (SE) is of 0.326lb.

81 seats

step-by-step explanation:

if you multiply 0.65 times 125 then you get 81.5 seats. well since you can't have half of a seat you have to round down and get 81 seats in the no children zones. that leave 44 seats outside of the no children zone.
