- Is blood pressure discrete or continuous quantitaive variable? Why?A low resting heart rate can mean a high degree of physical fitness, which is associated with reducedrates of cardiac events like heart attacks. By working out regularly in the gym, the heart becomes moreefficient, pumping the lowest amount of blood one needs when in a relaxed state. Normal resting heartrate for adults ranges from 60 to 100 beats per minute but a well-trained athlete can have a normal restingheart rate as low as 40 beats per minute. Dr. Castillejo wants to know if her gym members have attainedthis average resting heart rate of athletes. Use the R commander output below to address Dr. Castillejo’sconcern . Write a brief report about the analysis by identifying the set of hypotheses to be tested, theappropriate test to use, and implications and recommendations of/from the conclusions.Is Homework Truly Beneficial? Two decades ago, researchers believed that homework had a negative impact on students’ physical and emotional health, yet students are still bogged down with hours of homework as early as the second grade. According to research by several universities, elementary students spend an average of 3 hours a week doing homework. The same studies revealed that the average high school student spends over 22 hours a week on homework. In fact, students today spend more than double the time on homework than students two decades ago. Sadly, as time spent on homework doubles, student performance continues to decline. So, how then is homework helping? Homework is harmful and not the key to student success. 2 Select the correct answer. How does the writer introduce the claim? A. by using research to set the context for the argument against homework B. by telling a short personal story about her struggles with homework C. by comparing…
- Please solve for p value ,determine weather to reject hypothesis and state the conclusion for enough evidencePlease do not use Excel to find the answersA researcher has conducted a study to investigate the relationship between how important a person thinks appearance is and how much they spend on clothes each month, The first variable was 'self- rating of the importance of appearance' measured on a ten point scale (where 1 = not important and 10 = extremely important). The second variable was 'amount of money spent on clothes each month' measured by asking people to estimate to the nearest five pounds how much they spent in a typical month, The results are in the table below: Participant Self-rating of Amount spent on of clothes month (Maloti) s (initials) importance each appearance HP 6 80 EP 8 120 SF 100 PR 110 MS 75 JP 36 AG 15 BF 50 (a) Describe how an appropriate descriptive statistic could be used with the data in this table.

Find the probability that their product is not less than 3/4 times their greatest product.A typical treatment for Acinetobacter baumannii infection, for example, is a regimen of ampicillin, consisting of 250 mg, 4 times a day for 1 week. But antibiotics are used for a variety of medical issues by many people in the United States. Based on this information, estimate the weight, in kilograms, of ALL antibiotics ingested by people in the US each year. State any other assumptions and show all of your work.
