Answer:
The mean and the standard deviation of the sampling distribution of the number of students who preferred to get out early are 0.533 and 0.82
Step-by-step explanation:
According to the given data we have the following:
Total sample of students= 150
80 students preferred to get out 10 minutes early
Therefore, the mean of the sampling distribution of the number of students who preferred to get out early is = 80/150 = 0.533
Therefore, standard deviation of the sampling distribution of the number of students who preferred to get out early= phat - p0/sqrt(p0(1-p)/)
= 0.533-0.5/sqrt(0.5*0.5/15))
= 0.816 = 0.82
-8 - 7x is the factored version.

Answer:
8 turtles
Step-by-step explanation:
Each of Liam's sea turtle sculpture weighs 3\8 pounds and he ships them in a wooden box that weighs 2 pounds.
The weight of the box filled with the sea turtles is 5 pounds.
This means that the weight of the sea turtles in the wooden box is:
5 - 2 = 3 pounds
To find the number of sea turtles in the box, we simply divide the total weight of the turtles in the box by the weight of each turtle. That is:
= 8 turtles
There are 8 turtles in the box.
