Valerie is ordering salads and drinks for her friends. salads cost $7 each, drinks cost $3 each, and there is a $5 delivery char
Helen [10]

Since there is a $5 delivery charge, Valerie will surely spend those money.

Also, since a salad costs $7, and Valerie buys 3 of them, she will spend 21 more dollars.

So, salads and delivery charge sum up to 21+5 = 26

This means that Valerie has 50-26 = 24 dollars left. A drink costs $3, so she can buy

\dfrac{24}{3} = 7 drinks.

In each of the following scenarios, determine if the data are paired.
zmey [24]

Answer:

1. Can be Paired or Not Paired

2. Paired

3. Not Paired

Step-by-step explanation:

Two sets of observations are paired if each observation in one set has a special correspondence or connection with exactly one observation in the other data set.

1. Can be Paired or Not paired

Reason -

We might look at testing the difference of means using a two sample t-test. However, we may also try running a paired t-test.

But its used in cases where the observations are usually from the same populations at different times or through different sources etc.

Hence can't conclude that it is paired or not paired.

2. Paired

Reason -

Each record is a price of the same item from different stores.

3. Not paired

Reason -

This is again a case of testing the difference of means of two-samples (2 independent samples precisely) that are not paired.
