Incentives for Quitting Smoking: Do They Work? Exercise 5.31 describes a study examining incentives to quit smoking. With no inc

entives, the proportion of smokers trying to quit who are still abstaining six months later is about 0.06. Participants in the study were randomly assigned to one of four different incentives, and the proportion successful was measured six months later. Of the 498 participants in the group with the least success, 47 were still abstaining from smoking six months later. We wish to test to see if this provides evidence that even the smallest incentive works better than the proportion of 0.06 with no incentive at all. State the null and alternative hypotheses, and give the notation and value of the sample statistic. Use a randomization distribution and the observed sample statistic to find the p-value. Give the mean and standard error of the normal distribution that most closely matches the randomization distribution, and then use this normal distribution with the observed sample statistic to find the p-value. Use the standard error found from the randomization distribution in part (b) to find the standardized test statistic, and then use that test statistic to find the p-value using a standard normal distribution. Compare the p-values from parts (b), (c), and (d). Use any of these p-values to give the conclusion of the test.

Answer:

9. No

10. Yes

Step-by-step explanation:

The first one is not, since you have (3, 3) and (3, 9).  In a function, each x maps to a single y.

The second one is since every x appears only once.

a lakeis 200ft wide. two boats start to move towards one another from opposite shores.In one minute ,the first boat goes 40 ft a
IrinaVladis [17]

The distance between the boats after 1 minute would be 130 ft.

Given that a lake is 200ft wide, and two boats start to move towards one another from opposite shores, and in one minute, the first boat goes 40 ft and the second one goes 30 ft, to determine what would be the distance between the boats after 1 minute the following calculation must be performed:

  • Total width - boat distance 1 - boat distance 2 = Distance after 1 minute
  • 200 - 40 - 30 = X
  • 130 = X

Therefore, the distance between the boats after 1 minute would be 130 ft.

Carlos is draining an aquarium. The graph shows the amount of water ( in liters) in the aquarium versus time ( in minutes
olya-2409 [2.1K]

Using a linear function, we have that:

a) The amount of water in the aquarium at 0 minutes is of 300 liters.

b) As time increases, the amount of water decreases at a rate of 60 liters per minute.

<h3>What is a linear function?</h3>

A linear function is modeled by:

y = ax + b

In which:

  • a is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.
  • b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.

In this problem, we have that the y-intercept is of 300, hence the amount of water in the aquarium at 0 minutes is of 300 liters.

The amount <u>decreases 60 liters in a minute,</u> hence:

As time increases, the amount of water decreases at a rate of 60 liters per minute.
