Answer:
Using calculator: 0.0415
Using Z-score Table: 0.0418
Step-by-step explanation:
There are two ways you can solve this problem.
1. Use the normal distribution function on a calculator.
Entered values:
Lower Limit: 126
Upper Limit: 999999999999999... (To encompass all the data)
Standard Deviation: 15
Mean: 100
2. Find the Z score and look up probabilities on table.
Formula for Z score:
Z = 1.7333
This means that the value 126 is 1.733 standard deviations away from the mean. We can look this value up on the Z table to find its corresponding probability.
This will show us the probability of the random sampling being equal to or lower than 126.
P = 0.9582
So to find the probability of it being above, we simply just calculate the inverse as all probabilities on the curve = 1.
1-0.9582 = 0.0418
NOTE: Values found from the table will usually be a bit different from if you find it from a calculator, the one you need will depend on the method you use in class.
Hope this helped!
The price of each ball in a baseball bag would be 1.665 dollars
It is given that,
The cost price of a bag of baseball bag = 9.99 dollars
The number of balls in each bag = 6 baseballs
Now, we need to find the cost of one baseball if it were to sold individually
To find the cost of one quantity out of a bunch we divide the bunch price with the number of quantities in the bunch
Here, in this case
The cost price of each ball =
=
= 1.665 dollars
Hence, the price of each ball in a baseball bag would be 1.665 dollars
