OU--------wwNW 4.57 FDA REPORT ON PESTICIDES INFOOD. Periodically, the Food and DrugAdministration (FDA) produces a report as part ofits pesticide monitoring program. The FDA'sreport covers a variety of food items, each ofwhich is analyzed for potentially harmful chemicalcompounds. Recently, the FDA reported that nopesticides at all were found in 91% of thedomestically produced vegetable samples.(Pesticide Monitoring Program: Fiscal Year 2017Pesticide Report, US Food and DrugAdministration). Consider a random sample of 800vegetable items analyzed for the presence ofpesticides.a. Compute u and o for the random variablex, the number of vegetable items thatshowed no trace of pesticide.b. Based on a sample of 800 vegetable items,is it likely you would observe less than halfwithout any traces of pesticide? Explain.

Dental health issues remain a barrier to attendance, as evidenced by a 2010 Los Angeles School Attendance Review Board (SARB), which lists dental health, along with homelessness, in the top barriers to attendance. The Dental Hygiene program at West Los Angeles College collects data on its clinic patients to help instructors and students better understand their patient population. From July 2017 to December 2019 the program treated 3421 patients. Students were asked to analyze a random sample of 127 patients from that time period and found that 36.4% had severe periodontal disease (infections and inflammation of the gums and bone that surround and support the teeth). Identify the population: Identify the sample: Identify the parameter of interest: Identify the statistic:
According to the National Institute on Alcohol Abuse and Alcoholism (NIAAA) and the National Institutes of Health (NIH), 41% of college students nationwide engage in "binge-drinking" behavior: having five or more drinks on one occasion during the past two weeks. A college president wonders if the proportion of students enrolled at her college who binge drink is actually lower than the national proportion. In a commissioned study, 346 students are selected randomly from a list of all students enrolled at the college. Of these, 135 admit to having engaged in binge drinking.The college president is more interested in testing her belief that the proportion of students at her college who engage in binge drinking is lower than the national proportion of 0.41. What is the P-value? (Round your answer to four decimal places.) P-value =
A study prospectively examined whether sleep-disordered breathing was associated with an increased risk of death from any cause in a cohort of 600 adults participating in the Sleep Heart Health Study. Study participants were classified into four groups depending on the extent of their sleep-disordered breathing (none, mild, moderate, or severe). The counts of deaths over the course of the study are reported for each group in the following two-way table.

A governmental agency computed the proportion of violent crimes in the United States in a particular year falling into each of four categories. A simple random sample of 500 violent crimes committed in California during that year were categorized in the same way. The following table presents the results. Category U.S.Proportion CaliforniaFrequency Murder 0.018 4 Forcible Rape 0.07 35 Robbery 0.390 218 Aggravated Assault 0.522 243 Can you conclude that the proportions of crimes in the various categories in California differ from those in the United States as a whole? Use the 0.05 level of significance and the P-value method with the TI-84 Plus calculator. (b) Find the P-value. Round the answer to at least four decimal places.

Three Year Olds: 40, 35, 38, 39, 40, 50, 40, 38, 42 Four Year Olds: 35, 36, 39, 29, 35, 34, 33, 34, 35 a. Is there a significant difference in the motor skills from age three to four? Test with an α = 0.01. b. What type of error is possible based on the outcome? c. Calculate and interpret the effect size. d. What is the mean motor skill score for the age three children? What is the mean motor skill score for the age four children?
