The first thing to do is find the unit rate for both

Choice A: 6 oz for 1.49
To get 6 to 1 you have to divide by 6. What you do to one side you must do to the other... So:
1.49/6=0.2483333
Round to the nearest tenth. 0.25
Choice A unit price is 0.25

Choice B: 13 oz for 3.59
To get 13 to 1 you need to divide by 13. What you do to one side you must do to the other... So:
3.59/13=0.2761
Round to the nearest tenth. 0.28

Then compare the two. 
Answer: Choice B is a higher unit price. 

Hope this helps!

If the null hypothesis is inside the confidence interval, then the decision was likely to ________ using hypothesis testing.
ololo11 [35]

Answer:

B: Retain the null hypothesis

Step-by-step explanation:

In the relationship between the confidence interval and hypothesis, it is stated that:

When the confidence interval is constructed, all values that fall inside the interval are considered possible values for the parameter that we are estimating while values that fall outside the interval are rejected as they are considered not possible or realistic values.

Now, If the value of the parameter specified by the null hypothesis falls inside the given confidence interval, then we will fail to reject the null hypothesis at the corresponding significance level. However, If the value specified by the null hypothesis doesn't fall inside the given confidence interval, then the null hypothesis can be rejected at the corresponding significance level.

A card was selected at random from a standard deck of cards. The suit of the card was recorded, and then the card was put back i
cupoosta [38]

The relative frequency of selecting a diamond from 40 trials of selecting a random card is 30%.

<h3>What is relative frequency?</h3>

The relative frequency of an event is the ratio of total number of favorable or desired outcome to the total number of trails done.

Given information-

The card is selected random from the deck of cards.

Total number of trails is 40.

It is known that the total number of diamond card in a standard deck of card is 11. There is total 40 trials is done in which a random card is selected.

As the relative frequency is the ratio of total number of diamonds to the total number of trials done. Thus,

f_r=\dfrac{11}{40}\\f_r=0.3

In the percentage from,

f_r={0.3}\times100\\f_r=30

Thus the relative frequency of selecting a diamond from 40 trials of selecting a random card is 30%.
