Answer=7 minivans
45/7=6.4
since you can't have 0.4 minivans, we round up 6.4 to 7
Answer:
The z-score corresponding to an observed value of x of 2 is 0.215.
Step-by-step explanation:
We are given that a variable x has the possible observations shown below;
Possible observations of X: -3, -1, 0, 1, 1, 2, 4, 4, 5.
Firstly, we will find the mean and the standard deviation of X, i.e;
Mean of X, (
) =
=
=
= 1.44
Standard deviation of X, (
) =
=
= 2.603
Now, the z-score corresponding to an observed value of x of 2 is given by;
z-score =
=
= <u>0.215.</u>
Estimation- 16 plus 13 plus 9 plus 10 plus 18= 66 ounces
Exact- 65.43 ounces
There is a 60% chance that the product of the two numbers will be 7 because the numbers 1-6 are each 10% of the 100%.
