41,000Mean mileageIsing the dotplot and the sample mean mileage, is there convincing evidence that the new type of tread improvesne mileage of the tire?O Yes, because a mean mileage of 51,500 or more occurred only 14 out of 200 times, the mean mileage isstatistically significant. There is convincing evidence the new type of tire tread improves mileage of the tire.Yes, because a mean mileage of 51,500 or less occurred 186 out of 200 times, the mean mileage is statisticallysignificant. There is convincing evidence the new type of tire tread improves mileage of the tire.No, because a mean mileage of 51,500 or less occurred 186 out of 200 times, the mean mileage is notstatistically significant.

An agriculturalist on a farm conducted a study to investigate whether ladybugs are effective in reducing damage caused by moths to the fruit of avocado trees. The agriculturalist randomly sampled 66 avocado trees from the farm and paired them based on size. One tree from each pair was randomly assigned to a greenhouse with ladybugs, and the other tree in the pair was assigned to a greenhouse without ladybugs. After one month, the number of damaged avocado fruit on each tree was recorded. All other variables were held constant over the one month period. The difference in the number of damaged avocado fruit per tree pair (without ladybugs minus with ladybugs) was calculated for each of the 33 pairs and is shown in the stemplot. Consider a scenario in which 5 tree pairs are randomly selected one at a time, with replacement, from the sample of 33 tree pairs. Let the random variable T represent the number of tree pairs out of the 5 selected with a positive difference in number of damaged…

A hospital found out that there is a higher incidence of food poisoning in adults than in children. Thirty-four of the 250 adults and 16 of 275 children were food poisoned according to the hospital survey. Determine if there is enough evidence to believe the hospital claim. Use a 2.5% significance level.
The manufacturer of a new racecar engine claims that the proportion of engine failures due to overheating for this new engine, (p1), will be no higher than the proportion of engine failures due to overheating of the old engines, (p2). To test this statement, NASCAR took a random sample of 115 of the new racecar engines and 120 of the old engines. They found that 12 of the new racecar engines and 9 of the old engines failed due to overheating during the test. Does NASCAR have enough evidence to reject the manufacturer's claim about the new racecar engine? 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…
The manufacturer of a new racecar engine claims that the proportion of engine failures due to overheating for this new engine, (p1), will be no higher than the proportion of engine failures due to overheating of the old engines, (p2). To test this statement, NASCAR took a random sample of 135 of the new racecar engines and 175 of the old engines. They found that 14 of the new racecar engines and 8 of the old engines failed due to overheating during the test. Does NASCAR have enough evidence to reject the manufacturer's claim about the new racecar engine? Use a significance level of α=0.01 for the test. Step 3 of 6 : Compute the weighted estimate of p, p‾. Round your answer to three decimal places.

According to YCharts in 2018, the unemployment rate for 15- to 24-year-olds in British Columbia was reported to be 9.4% for July, 2018 specifically. Suppose that this report was based on a random sample of four hundred 15- to 24-year-olds. A political campaign manager wants to know if the sample results can be used to conclude that the unemployment rate for 15- to 24-year-old British Columbians is significantly higher than the unemployment rate for all adults in British Columbia based on a significance level α=0.05 α=0.05. According to the Statistics Canada, the unemployment rate for all adults in British Columbia was 5.0% in July 2018. State the hypotheses. Calculate the test statistic. Use Excel to find the p-value. Hint: Use NORM.DIST. What is your hypothesis test decision? What is your conclusion in the context of the application?
Researchers report that university students who are on Twitter or have it running in the background) while studying had lower grades than students who did not use the social network. A researcher would like to know if the same result extends to students in lower grade levels. The researcher planned a two-factor study comparing Twitter users with non-users for primary school students, high school students, and university students. For consistency across groups, grades were converted into six categories, numbered 0–5 from low to high. The results are presented in the following matrix. Use a two factor ANOVA with α =.05 to evaluate the mean differences and answer the following questions:Q.5.1.What are the dependent and independent variables in this study?Q.5.2.State the alternate hypotheses for this test.Q.5.3.What were the assumptions for this statistical test and were they met? Q.5.4.Does using twitter have an influence on student’s grades across all ages? Were there any significant…
A recent study claims that using music in a class enhances concentration and consequently helps students absorb more information. A researcherdecided to test this claim on a smaller group of randomly selected students from three different classes. Each classroom was provided with a different environment for students to study. Classroom A had constant music being played in the background, classroom B had variable music being played and classroom C was a regular class with no music playing. After one month, the researcher conducted a test for all the three groups and ranked their scores. What statistical test would be most appropriate for testing the research hypothesis? Explain your answer.
A random sample of 1100 potential voters was randomly divided into 2 groups. Group 1: 500 potential voters; no registration reminders sent; 248 registered to vote Group 2: 600 potential voters; registration reminders sent; 332 registered to vote Do these data support the claim that the proportion of voters who registered was greater in the group that received reminders than in the group that did not? Use a 1% level of significance.
