A concerned group of citizens wanted to know if theproportion of armed robberies in Texas was different in2011 than in 2010. Their research showed that of the113,231 violent crimes in Texas in 2010, 7,622 of themwere armed robberies. In 2011, 7,439 of the 104,873violent crimes were in the armed robbery category.Test at a 5% significance level.a) The null and alternative hypothesis would be:Ho:μ2010 = μ2011H1:/2010 < /2011Ho: p2010H1: P2010Ho: 2010H₁ 2010p=Ho: P2010H₁: P2010P20112 = -3.33P2011O Ho: P2010 = P2011H1: P2010P201120112011d) Make a decision.P2011O Ho: 2010/2011Ηι:μ2010 > μ2011b) Determine the test statistic.

Are freshmen psychology majors just as likely to change their major before they graduate compared to freshmen business majors? 366 of the 673 freshmen psychology majors from a recent study changed their major before they graduated and 394 of the 705 freshmen business majors changed their major before they graduated. What can be concluded at the a = 0.10 level of significance? For this study, we should use z-test for the difference between two population proportions a. The null and alternative hypotheses would be: Ho: p1 p2 v (please enter a decimal) H1: p1 p2 (Please enter a decimal) b. The test statistic z v -0.508 X (please show your answer to 3 decimal places.) c. The p-value = 0.6115 X (Please show your answer to 4 decimal places.) d. The p-value is > vV a e. Based on this, we should fail to reject the null hypothesis. f. Thus, the final conclusion is that ... O The results are statistically significant at a = 0.10, so there is sufficient evidence to conclude that the proportion of…
In one study of smokers who tried to quit smoking with nicotine patch therapy, 38 were smoking one year after treatment and 33 were not smoking one year after the treatment. Use a 0.01 significance level to test the claim that among smokers who try to quit with nicotine patch therapy, the majority are smoking one year after the treatment. Do these results suggest that the nicotine patch therapy is not effective? Null and alternative hypotheses for this test.

Is there an association between daily screen time and exercise habits in high school students? Mia selects a random sample of 123 high school students and categorizes them into 1 of 3 categories of screen time and whether they exercise. She would like to determine if there is convincing evidence of an association. Let = 0.05. What are the hypotheses for this test?

According to the Bureau of Transportation Statistics, on-time performance by airlines is described as follows: Action % of time On Time National Aviation System Delay Aircraft arriving late 71 9. 10 Other (weather and other conditions) 10 When a study was conducted it was found that of the 211 randomly selected flights, 150 were on time, 19 were a National Aviation System Delay, 21 arriving late , 21 were due to weather. Perform a test to see if there is sufficient evidence at a = 0.10 to see if these differ from the governments statistics. The correct hypotheses are: O Ho: The sample is a good fit to the Bureau of Transportation Statistics. HA: The sample is not a good fit to the Bureau of Transportation Statistics. (claim) O Ho: The sample is not a good fit to the Bureau of Transportation Statistics. HA: The sample is a good fit to the Bureau of Transportation Statistics.

In a previous poll, 29 % of adults with children under the age of 18 reported that their family ate dinner together seven nights a week. Suppose that, in a more recent poll, 303 of 1113 adults with children under the age of 18 reported that their family ate dinner together seven nights a week. Is there sufficient evidence that the proportion of families with children under the age of 18 who eeat dinner together seven nights a week has decreased? Use the a 0.01 significance level. Because npo(1-PO) 10 and thee sample size is greater than 5% of the population size, and the sample can be reasonably assumed to be random the requirements for testing the hypothesis are not satisfied (Round to one decimal place as needed.) What are the null and alternative hypotheses? 29 versus H 29 Ho H (Type integers or decimals. Do not round.) Find the test statistic, zn- zo (Round to two decimal places as needed.) Find the P-value.
