Chapter 5: Q 10. (page 294)

Cold weather coming to A TV weather man, predicting a colder-than-normal winter, said, 鈥淔irst, in looking at the past few winters, there has been a lack of

really cold weather. Even though we are not supposed to use the law of averages, we are due.鈥� Do you think that 鈥渄ue by the law of averages鈥� makes sense in talking about the weather? Why or why not?

Short Answer

Expert verified

No, it is not used.

Step by step solution

01

Step 1. Given Information  

The term "according to the law of averages" makes sense when discussing the weather.

02

Step 2. Concept Used  

The Law of averages works well over large data sets, but while talking about weather, there are very frequent changes that make it difficult to fit them into the Law of Average.

03

Step 3. Explanation  

Because the current year's weather is not independent of the previous year's weather, and the sample size of a few winters is simply too small to apply the rule of averages, the phrase "according to the law of averages" has no meaning when discussing weather. As a result, we avoid using the phrase "according to the law of averages" when addressing meteorological conditions.

Recycling Do most teens recycle? To find out, an AP Statistics class asked an SRS of 100 students at their school whether they regularly recycle. How many students in the sample would need to say 鈥淵es鈥� to provide convincing evidence that more than half of the students at the school recycle? The Fathom dot plot below shows the results of taking 200 SRSs of 100 students from a population in which the true proportion who recycle is 0.50.

(a) Suppose 55 students in the class鈥檚 sample say 鈥淵es.鈥� Explain why this result does not give convincing evidence that more than half of the school鈥檚 students recycle.

(b) Suppose 63 students in the class鈥檚 sample say 鈥淵es.鈥� Explain why this result gives strong evidence that a majority of the school鈥檚 students recycle.

Who eats breakfast? Refer to Exercise 49.

(a) Construct a Venn diagram that models the chance process using events B: eats breakfast regularly, and M: is male.

(b) Find P(B鈭�M) Interpret this value in context.

(c) Find P(Bc鈭�Mc) Interpret this value in context.

Fill 鈥檈rr up! In a recent month, 88%of automobile drivers filled their vehicles with regular gasoline, 2%purchased midgrade gas, and 10%bought premium gas.17 Of those who bought regular gas, 28% paid with a credit card; of customers who bought midgrade and premium gas, 34% and 42%, respectively, paid with a credit card. Suppose we select a customer at random.

Draw a tree diagram to represent this situation. What鈥檚 the probability that the customer paid with a credit card? Use the four-step process to guide your work.

At the gym Suppose that 10%of adults belong to health clubs, and 40% of these health club members go to the club at least twice a week. What percent of all adults go to a health club at least twice a week? Write the information given in terms of probabilities, and use the general multiplication rule.

Treating low bone density (4.2) Fractures of the spine are common and serious among women with advanced osteoporosis (low mineral density in the

bones). Can taking strontium ranelate help? A large medical trial assigned 1649 women to take either strontium ranelate or a placebo each day. All of

the subjects had osteoporosis and had had at least one fracture. All were taking calcium supplements and receiving standard medical care. The response variables were measurements of bone density and counts of new fractures over three years. The subjects were treated at 10 medical centers in 10 different countries.9 Outline an appropriate design for this experiment. Explain why this is the proper design.
