In a survey, 716 out of 1132 randomly selected adults in the United States said that they use cell phones while driving. a) Use a 0.02 significance level when testing the claim that the proportion of adults who use cell phones while driving is different than 70%. b) What does the conclusion mean?
The drug Ritalin is designed to stimulate the central nervous system. In a random sample of 252 boys aged ten – twelve years old, it was found that 44 of the boys were taking Ritalin. It is known that the proportion of all boys aged 13 – 15 who take Ritalin is 24%. A researcher claims that the population proportions of boys who take Ritalin aged 10 – 12 is different than boys aged 13 – 15. Can you support this claim at the 5% significance level? a. Conduct a hypothesis test to test the claim at the 5% significance level. Be sure to state you Ho and Ha, your test statistic and p-value, whether or not you reject Ho and whether you support the claim. b. Show that you can use the large sample methodology. c. Write a complete sentence describing what a Type I error is in context.
A computer manufacturer believes that the proportion of hardware malfunctions is different in humid climates than in dry climates. To test this claim, the manufacturer takes a random sample of 400 machines sold in Florida (humid) and 400 machines sold in Arizona (dry). The manufacturer finds that 44 of the machines in Florida and 24 of the machines in Arizona had hardware malfunctions. d. Does the evidence support the computer manufacturer's claim at the 10% significance level?
To compare the wearing of two types of automobile engines, 1 and 2, an experimenter chose to "pair" the measurements, comparing the wear for the two types of engines on each of 7 automobiles, as shown below. Determine whether these data are sufficient to infer at the 10% significance level that the two types of engines wear differently. The null and alternative hypotheses are:
Kevin, a Human Resources professional, would like to make the claim that the average hourly wage for administrative workers at his company is less than $9.69. Kevin samples 15 workers and obtains a sample mean of $8.80 per hour. At the 1% significance level, should Kevin reject or fail to reject the null hypothesis given the sample data below?
A Gallup poll to survey the top concerns of Americans was conducted. Suppose that 566 women and 465 men were independently and randomly selected and that 322 women and 172 men chose the state of the economy as their biggest concern. Can we conclude that the proportion of women ( p1 ), choosing the state of the economy as their biggest concern, exceeds the proportion of men ( p2 )? Use a significance level of α=0.1 for the test. Step 1 of 6 : State the null and alternative hypotheses for the test. Step 2 of 6 : Find the values of the two sample proportions, pˆ1p^1 and pˆ2p^2. Round your answers to three decimal places. Step 3 of 6 : Compute the weighted estimate of p, p‾p‾. Round your answer to three decimal places. Step 4 of 6 : Compute the value of the test statistic. Round your answer to two decimal places. Step 5 of 6 : Determine the decision rule for rejecting the null hypothesis H0H0. Round the numerical portion of…
A national publishing house claims that 45% of all weekly magazine readers in South Africa read their publication. Test this claim at the 5% significance level, if a survey found that 205 out of a random sample of 500 magazine readers said that they read the relevant publication.
A sample of 45 households reveals that 23% have traveled overseas. Is this significantly different from a hypothesized value of 30%, which characterizes the entire country? Use a significance level of 0.05. Write down the null and alternative hypotheses, find the test statistic and the p-value, and state your conclusion.
An ice-cream manufacturer asked you to determine if a person's choice of ice-cream flavour is dependent on age variability. To do this, you conduct a Chi-square hypothesis test with a calculated test statistic of 12.1812 and a critical value of 15.057 at a 5% significance level. Using the information provided, how would you advise the ice-cream manufacturer? Choosen one: A. Reject the null hypothesis, ice-cream choice does not depend on age variability. B. Do not reject the null hypothesis, ice-cream choice depends on age variability. C. Reject the null hypothesis, ice-cream choice depends on age variability. D. Do not reject the null hypothesis, ice-cream choice does not depend on age variability
