2. Perform a hypothesis test, then make a conclusion about the claim:

A consumer research organization states that the mean time a US adult spends on their computer per day is more than 5.2 hrs. You want to test this claim. You find that a random sample of 20 US adults spend a mean of 5.5 hrs on their computers per day. Assume the population standard deviation is 1.1 hrs. At ? = .02, can you support the research organization’s claim?

A consumer research organization states that the mean caffeine content per 12-ounce bottle of a population of caffeinated soft drinks is 37.8 milligrams. You find a random sample of 48 12-ounce bottles of caffeinated soft drinks that has a mean caffeine content of 41.5 milligrams. Assume the population standard deviation is 12.5 milligrams. At α=0.05, what type of test is this and can you reject the organization’s claim using the test statistic?

Identify the null hypothesis, alternative hypothesis, test statistic, P-value, conclusion about the null hypothesis, and final conclusion that addresses the original claim. Use the P-value method. A simple random sample of 55 adults is obtained from a normally distributed population, and each person’s red blood cell count (in cells per microliter) is measured. The sample mean is 5.26 and the sample standard deviation is 0.54. Use α = .07 to test the claim that the sample is from a population...

A manual states that in order to be a​ hit, a song must be no longer than three minutes and thirty seconds​ (or 210 ​seconds). A simple random sample of 50 current hit songs results in a mean length of 250.0 sec. Assume the population standard deviation of song lengths is 54.5 sec....

You will perform a Chi-Square test and an ANOVA test. For each hypothesis test make sure to report the following steps: Identify the null hypothesis, Ho, and the alternative hypothesis, Ha. Determine whether the hypothesis test is left-tailed, right-tailed, or two-tailed. Find the critical value(s) and identify the rejection region(s). Find the appropriate standardized test statistic. If convenient, use technology. Decide whether to reject or fail to reject the null hypothesis. Interpret the decision in the context of the original...

State your conclusion to the hypothesis test. A national organization has been working with utilities throughout the nation to find sites for large wind machines that generate electricity. Wind speeds must average more than 22 miles per hour (mph) for a site to be acceptable. Recently, the organization conducted wind speed tests at a particular site. Based on a sample of n=33 wind speed recordings (taken at random intervals), the wind speed at the site averaged 22.8 mph, with a...

In a market research study, members of a consumer test panel are asked to rate the visual appeal (on a 1 to 10 scale) of the texture of dashboard plastic trim in a mockup of a new fuel cell car. The manufacturer is testing four finish textures. Panelists are assigned randomly to evaluate each texture. The test results are shown below. Each cell shows the average rating by panelists who evaluated each texture. Research question: Is mean rating affected by...

A consumer research group is interested in testing an automobile manufacturer’s claim that a new economy model will travel at least 25 miles per gallon of gasoline. Provide a null and alternative hypothesis for the test. Suppose a test on 25 cars of this model indicates an average of 24 mpg, with a sample standard deviation of 3 mpg. Compute the value for the test statistic and the p-value. Please copy your R code and the result and paste them...
