The 2019-2020 flu season was especially tough.By the end of the season, an estimated total of 49 million people in the United States had contracted the flu, of whom an estimated 79,000 died from the flu. Assume that the US population was 300,000,000 during the 2019-2020 flu season and that during the season, a total of 2.9 million Americans died from all causes (including the flu). Assume the population of the US remained the same at the midpoint of the season. Report mortality rates per 100,000. Be sure to express the measure in the correct format. c.What was the flu-related mortality rate during the 2019-2020 flu season? d.What is the all-cause mortality rate during the 2019-2020 flu season? e.In a country with an age distribution that is much younger than in the US, the proportionate mortality rate from flu in 2019 was 5%. Based on this information alone, can we determine that the risk of dying from flu in 2019 was higher in this country compared to the US? Why or why not?
A researcher suspects that the actual prevalence of generalized anxiety among children and adolescents is higher than the previously reported prevalence of generalized anxiety disorder among children and adolescents. The previously reported prevalence of generalized anxiety disorder among children and adolescents is 3.9%, and the researcher conducts a study to test the accuracy of the previously reported prevalence of generalized anxiety disorder by recruiting 98 children and adolescents from various pediatricians’ offices and tests them for generalized anxiety disorder using the DSM-5. The researcher determines that the prevalence of generalized anxiety disorder among the participants of the study is 6.1%. Calculate the z value for the test statistic. A) z = 1.12 B) z = 1.09 C) z = 0.92 D) z = -57.53
In an article in the Journal of Marketing, Bayus studied the differences between "early replacement buyers" and "late replacement buyers" in making consumer durable good replacement purchases. Early replacement buyers are consumers who replace a product during the early part of its lifetime, while late replacement buyers make replacement purchases late in the product's lifetime. In particular, Bayus studied automobile replacement purchases. Consumers who traded in cars with ages of zero to three years and mileages of no more than 35,000 miles were classified as early replacement buyers. Consumers who traded in cars with ages of seven or more years and mileages of more than 73,000 miles were classified as late replacement buyers. Bayus compared the two groups of buyers with respect to demographic variables such as income, education, age, and so forth. He also compared the two groups with respect to the amount of search activity in the replacement purchase process. Variables compared…
Question 7 Immuno-oncologists wanted to examine whether combination therapy with nivolumab and ipilimumab improved survival in melanoma patients compared to treatment with ipilimumab alone. They plan to first obtain approval from the institutional review board, identify melanoma patients, randomly assign some patients to combination therapy and others to treatment with ipilimumab alone, and follow these patients a certain period of time to record their survival. This study is an example of (Choose one from choices given): O None of the choices are correct O Experimental design (aka: interventional) O Non-Experimental design (aka: observational O Survey design
Thomas and Camille are international visiting scientists with research interests in horticultural and environmental issues in urban areas. They participate in various studies performed by Ville de Montréal. More specifically, they address issues related to plant diseases in city gardens, air and water quality, and food waste management. The viruses causing problems in strawberry plants are mainly spread by one insect, the strawberry aphid. Camille believes that as aphids feed on leaves, they transmit viruses that can cause a rapid decrease in plant growth. She decides to verify whether or not the number of strawberry aphids found on a plant could be linked to its growth. She therefore randomly chooses 5 strawberry plants at the same stage of development in a virus-infested garden. For each individual plant, she first collects all the aphids present on the plant and weighs them, and then weighs the entire plant to have a measure of plant growth. She obtains the following data.…

More than 10% of people carry the parasite Toxoplasma gondii. The life-long presence of Toxoplasma cysts in neural and muscular tissues leads to prolongation of reaction times in infected subjects. The following table gives data from Prague on 15- to 29-year-old drivers who had been and had not been involved in accidents. The table also gives the number of drivers who were infected with Toxoplasma gondii and who were uninfected.

Beryllium is an extremely lightweight metal that is used in many industries, such as aerospace and electronics. Long-term exposure to beryllium can cause people to become sensitized. Once an individual is sensitized, continued exposure can result in chronic beryllium disease, which involves scarring of the lungs. In a study of the effects of exposure to beryllium, workers were categorized by their duration of exposure (in years) and by their disease status (diseased, sensitized, or normal). The results were as follows: Duration of Exposure <1 1 to <5 ≥5 Diseased 14 13 18 Sensitized 11 20 15 Normal 78 140 209 Test the hypothesis of independence. Use the a=0.10 level of significance and the P-value method with the TI-84 Plus calculator. What do you conclude? State the null and alternate hypotheses.
2. Many people take ginkgo supplements advertised to improve memory. Are these over-the- counter supplements effective? In a study, elderly adults were assigned to the treatment group or control group. The 104 participants who were assigned to the treatment group took 40 mg of ginkgo 3 times a day for 6 weeks. The 115 participants assigned to the control group took a placebo pill 3 times a day for 6 weeks. At the end of 6 weeks, the Wechsler Memory Scale was administered. Higher scores indicate better memory function. Summary values are given in the following table: a) Based on these results, is there evidence that taking 40mg of ginkgo 3 times a day is effective in increasing mean performance on the Wechsler Memory Scale?b) Write a brief report on your findings
You are conducting a hypothetical retrospective study on use of plastics and prevalence of current medical problems in students. You hypothesize that participants who used more plastic cups in high school will exhibit more medical problems today. You ask all PH1 students to recall how many times they drank out of plastic cups in high school. Your participants struggle to recall this information and end up guessing how often they used plastic drinking containers in high school. Your study design will be negatively impacted by: (select one) A. Misrepresentation B. Recall error C. Negative associations D. Recall bias
The World Health Organization declared the novel coronavirus (COVID-19) outbreak a global pandemic on March 11, 2020. How did population movement change before and after the COVID-19 pandemic was declared? The United States' Bureau of Transportation has collected data that can help answer this question. In this activity we will focus on traveling patterns in the state of New York during 2019 and the first three seasons of 2020. The dataset consists of variables for the state of New York including the month the data were collected, a season year label, and the number of trips less than 1 mile from one's home as measured by a mobile device's movement. A trip is defined as movements that include a stay of longer than 10 minutes at an anonymized location away from home. Movements with multiple stays of longer than 10 minutes before returning home are counted as multiple trips. The months January, February, and March are categorized as winter; the months April, May and June are categorized…
