Karina owns a bakery where she orders both green apples and red apples to use in her baked goods. The supplier of the green appl

es says that 8% of their green apples are bruised. The supplier of the red apples says that 6% of their red apples are bruised.
Each week, Karina orders 120 of each type of apple, and she looks at the difference (Green−Red) between the proportions of apples with bruises in each order.

What will be the shape of the sampling distribution of the difference in sample proportions, and why?

A. Approximately normal, because we expect 10 bruised and 110not-bruised in both orders, and all of these counts are at least 10.
B. Approximately normal, because we expect 16 bruised and 104 not-bruised green apples, and 12 and 108 for the red apples, and all of these counts are at least 10
C. Not normal, because we expect fewer than 10 bruised apples in both orders.
D. Not normal, because we expect fewer than 10 not-bruised apples in both orders.

Let event A = You roll an even number on the first cube.Let event B = You roll a 6 on the second cube.Are the events independent
Gnesinka [82]

The events are independent. By definition, it means that knowledge about one event does not help you predict the second, and this is the case: even if you knew that you rolled an even number on the first cube, would you be more or less confident about rolling a six on the second? No.

An example in which two events about rolling cubes are dependent could be something like:

Event A: You roll the first cube

Event B: The second cube returns a higher number than the first one.

In this case, knowledge on event A does change you view on event B (and vice versa): if you know that you rolled a 6 on the first cube you don't want to bet on event B, while if you know that you rolled a 1 on the first cube, you're certain that event B will happen.

Conversely, if you know that event B has happened, you are more likely to think that the first cube rolled a small number, and vice versa.

A number increases by 10%, and then decreases by 10%. Will the result be greater than, less than, or equal to the original numbe
elena-s [515]
Given that the number is x,
10% increase will give us a new number of:
110/100*x
=1.1x
10% decrease will give us a new number of:
90/100*1.1x
=0.99x
This implies the new number is less than the original number
