Chapter 9: Q. 37 (page 538)

Does the shaded region represent a low or a high p-value compared to a level of significance of 1%?

Short Answer

Expert verified

The shaded region represents a lower p-value.

Step by step solution

01

Given information

The figure is given.

02

Explanation

Typically, the hypothesis test is carried out on a sample of data from a broader population. This test is used to generate results from sample data based on a hypothesis.

A normal distribution is represented by the bell-shaped curve in the example above. The normal distribution is a continuous probability distribution with a bell-shaped form in which all values cluster towards the mean.

The shaded section of the presented figure reflects the p-value, which is a low-level value when compared to the importance of 1 percent because the p-value is zero, which suggests that the claim will not climb above 15cm on average. As a result, 0% of claims can be as high as 17cm, but the shaded area is at a low level, thus the claim will be lower.

For Americans using library services, the American Library Association claims that at most 67% of patrons borrow books. The library director in Owensboro, Kentucky feels this is not true, so she asked a local college statistic class to conduct a survey. The class randomly selected 100 patrons and found that 82borrowed books. Did the class demonstrate that the percentage was higher in Owensboro, KY? Use 伪=0.01 level of significance. What is the possible proportion of patrons that do borrow books from the Owensboro Library?

According to the Center for Disease Control website, in 2011 at least18%of high school students have smoked a cigarette. An Introduction to Statistics class in Davies County,KY conducted a hypothesis test at the local high school (a medium sized鈥揳pproximately 1,200 students鈥搒mall city demographic) to determine if the local high school鈥檚 percentage was lower. One hundred fifty students were chosen at random and surveyed. Of the150 students surveyed, 82have smoked. Use a significance level of 0.05 and using appropriate statistical evidence, conduct a hypothesis test and state the conclusions.

You are performing a hypothesis test of a single population proportion. The data come from which distribution ?

La Leche League International reports that the mean age of weaning a child from breastfeeding is age four to five worldwide. In America, most nursing mothers wean their children much earlier. Suppose a random survey is conducted of 21 U.S. mothers who recently weaned their children. The mean weaning age was nine months (3/4 year) with a standard deviation of 4 months. Conduct a hypothesis test to determine if the mean weaning age in the U.S. is less than four years old.

Over the past few decades, public health officials have examined the link between weight concerns and teen girls' smoking. Researchers surveyed a group of 273 randomly selected teen girls living in Massachusetts (between 12 and 15 years old). After four years the girls were surveyed again. Sixty-three said they smoked to stay thin. Is there good evidence that more than thirty percent of teen girls smoke to stay thin? The alternative hypothesis is:
