A marketing survey involves product recognition in New York and California. Of 558 New Yorkers surveyed, 193 knew the product while 196 out of 614 Californians knew the product. At the 0.05 level of significance, test the claim that the recognition rates are different. ( less or greater )
A group of health conscious researchers were interested in ways to lower blood pressure. The study consisted of 90 participants. 30 participants were randomly assigned to eat a heart healthy diet, 30 were randomly assigned to a heart healthy exercise routine, and 30 were randomly assigned to do nothing and serve as a control. After a month of their assigned intervention, participants' blood pressure was measured. Which statistical test should be used to compare the 3 intervention types on post-treatment blood pressure? df between= ? df within= ? df total= ?
Reports show that 92% of online searches in March 2021 use Google as the search engine. A network administrator wants to determine whether the percentage of searches that use Google is different in their company. They sample 800 searches and find that 758 of them use Google. Can they conclude that the percentage of searches that use Google in this company differs from 92%? Use the a = 0.05 level of significance.
Adverse reactions of a drug used to help patients continue their abstinence from the use of alcohol have been studied in clinical trials, and the accompanying table summarizes results for digestive system effects among patients from different treatment groups. Use a 0.05 significance level to test the claim that experiencing an adverse reaction in the digestive system is independent of the treatment group. Does the drug treatment appear to have an effect on the digestive system? Click the icon to view the data on adverse reactions from treatments. Determine the null and alternative hypotheses. OA. Ho: Drug treatment and adverse effects are not independent. H₁: Drug treatment and adverse effects are independent. OB. Ho: The drug treatment results in adverse effects on the digestive system.

Inadequate exposure to outdoor lighting conditions may increase the risk of myopia in children. A study was designed to estimate the rates of myopia among young children (6-7 years old) in Australia. A random sample of 124 young children in Australia was selected, and the researchers found that 7 of them had myopia. The researchers are interested in testing whether the proportion of myopia among young children in Australia is above 4%. What are the null and alternative hypotheses? [Select ) What is the test statistic? [ Select] What is the correct conclusid if our alpha value is 0.05? Select from below [ Select ] A. Our test statistic is more extreme than our critical value of 1.645. We reject the null hypothesis and conclude that more than 4% of Australian young children has myopia. B. Our test statistic is less extreme than our critical value of 1.645. We fail to reject the null hypothesis and cannot conclude that more than 4% of Australian young children has myopia. C. Our test…
A researcher was interested in how the effects of stress were different in people with our without military training. A equal number of participants were recruited that either had no military experience or had completed military experience. All participants were asked to give a speech without preparation while being judged by a panel of experts. Their heart rates were monitored during the speech and an average heart rate was calcuated for each participant. Which statistical test would be best to determine if there is a significant difference between groups? one-sample t-test dependent samples t-test independent samples t-test ANOVA
Internet addiction has been described as excessive and uncontrolled Internet use. The authors of a research article used a score designed to measure the extent and severity of Internet addiction in a study of 837 male and 874 female sixth-grade students in China. Internet Addiction was measured using Young's Internet Addiction Diagnostic Test. The lowest possible score on this test is zero, and higher scores indicate higher levels of Internet addiction. For the sample of males, the mean Internet Addiction score was 1.51 and the standard deviation was 2.02. For the sample of females, the mean was 1.01 and the standard deviation was 1.67. For purposes of this exercise, you can assume that it is reasonable to regard these two samples as representative of the population of male Chinese sixth-grade students and the population of female Chinese sixth grade students, respectively. The standard deviation is greater than the mean for each of these samples. Explain why it is not reasonable to…
