While her husband spent 2½hours picking out new speakers, a statistician decided to determine whether the percent of men who enjoy shopping for electronic equipment is higher than the percent of women who enjoy shopping for electronic equipment. The population was Saturday afternoon shoppers. Out of67men, 24said they enjoyed the activity. Eight of the 24 women surveyed claimed to enjoy the activity. We need to interpret the results of the survey .

Short Answer

Expert verified

There is insufficient data to establish that the proportion of males who enjoy shopping for electronic equipment is greater than the proportion of women at the5% level of significance.

Step by step solution

01

Given information

Given in the question that, While her husband spent 2½ hours picking out new speakers, a statistician decided to determine whether the percent of men who enjoy shopping for electronic equipment is higher than the percent of women who enjoy shopping for electronic equipment. The population was Saturday afternoon shoppers. Out of 67 men, 24said they enjoyed the activity. Eight of the 24 women surveyed claimed to enjoy the activity. We need to interpret the results of the survey .

Explanation

a. The null hypothesis

b. Alternative hypothesis

pm>pw.

c. The proportions of men and women are the random variable.

d. Two proportions with a normal distribution.

e. Fill in all requirements using Minitab's two-sample t test option.

The result will be

0.22is the test statistics

f. The output has a p-value of 0.517.

g .Graph the p-value matching region(s).

i.α=0.05

ii. Conclusion: the null hypothesis should not be rejected.

iii. Justification for Decision:

p-value<α.

iv. Conclusion: There is insufficient data to establish that the proportion of males who enjoy shopping for electronic equipment is greater than the proportion of women at the5%level of significance.

find the p-value?

Use the following information to answer next five exercises. A study was conducted to test the effectiveness of a juggling class. Before the class started, six subjects juggled as many balls as they could at once. After the class, the same six subjects juggled as many balls as they could. The differences in the number of balls are calculated. The differences have a normal distribution. Test at the \(1 \%\) significance level.

State the null and alternative hypotheses.

Use the following information to answer the next five exercises. A researcher is testing the effects of plant food on plant growth. Nine plants have been given the plant food. Another nine plants have not been given the plant food. The heights of the plants are recorded after eight weeks. The populations have normal distributions. The following table is the result. The researcher thinks the food makes the plants grow taller.

Draw the graph of the p-value.

Use the following information to answer the next twelve exercises. In the recent Census, three percent of the U.S. population reported being of two or more races. However, the percent varies tremendously from state to state. Suppose that two random surveys are conducted. In the first random survey, out of 1,000 North Dakotans, only nine people reported being of two or more races. In the second random survey, out of 500 Nevadans, 17 people reported being of two or more races. Conduct a hypothesis test to determine if the population percents are the same for the two states or if the percent for Nevada is statistically higher than for North Dakota.

In words, define the random variable for this test.
