An article in Medicine and Science in Sports and Exercise "Maximal Leg-Strength Training Improves Cycling Economyin Previously Untrained Men," (2005, Vol. 37 pp. 131-1236) studied cycling performance before and after eightweeks of leg-strength training. Seven previously untrained males performed leg-strength training three days perweek for eight weeks (with four sets of five replications at 85% of one repetition maximum). Peak power duringincremental cycling increased to a mean of 315 watts with a standard deviation of 16 watts. Construct a 99% two-sided confidence interval for the mean peak power after training. Assume population is approximately normallydistributed.Round the answers to 2 decimal places.i

PM Wed Nov 3 Stats Home Insert Draw View 8). Studies have shown that drivers who use cell phones while operating a motor passenger vehicle increase their risk of an accident. To quantify this risk, the New England Journal of Medicine (January 2, 2014) reported on the risk of a crash (or near crash) for both novice and expert drivers when using a cell phone. In a sample of 371 cases of novices using a cell phone while driving, 24 resulted in a crash (or near crash). In a sample of 1,467 cases of experts using a cell phone while driving. 67 resulted in a crash (or near crash). a). Find a 93% confidence interval for p, the true crash risk (probability) for novice drivers, also indicating the ME value. Answer: ME = b). Find a 93% confidence interval for p, the true crash risk (probability) for expert drivers, also indicating the ME value. Answer: гр, ME =
Question The relationship between United States unemployment and inflation rates during the Covid-19 pandemic. Background The covid-19 pandemic has led to higher unemployment rates in the United States than normal because many people were laid off jobs in response to the pandemic (Al-Fadly, 2020). It is important to analyze how such as sharp increase in unemployment affected inflation in relation to how unemployment have traditionally affected inflation. The overall relationship between unemployment and inflation has traditionally been an inverse one. It is argued that when unemployment rates are higher, the number of individuals who are looking for jobs usually becomes higher than the number of job positions that are available (Putnam & Azzarello, 2015). In such a situation, employers tend to pay lower wages because there is abundance of workers which naturally leads to a lower wage inflation. This study will examine the relationship between unemployment rates and inflation…
The paper “Playing Active Video Games Increases Energy Expenditure in Children” (Pediatrics[2009]: 534–539) describes an interesting investigation of the possible cardiovascular benefits of activevideo games. Mean heart rate for healthy boys age 10 to 13 after walking on a treadmill at 2.6 km/hour- for 6 minutes is 98 beats per minute (bpm). For each of the 14 boys, heart rates was measured after 15minutes of playing Wii Bowling. The resulting sample mean and standard deviation were 101 bpm and 15 bpm, respectively. For purposes of this exercise, assume that it is reasonable to regard the sample ofboys as representative of boys aged 10 to 13 and that the distribution of heart rates after 15 minutes of Wii Bowling is approximately normal.a) Does the sample provide convincing evidence that the mean heart rate after 15 minutes of WiiBowling is different from the known mean heart rate after 6 minutes of walking on the treadmill? Carry out a hypothesis test using an α = 0.01.b) The known…
Recently findings have been reported from a prospective cohort study that demonstrated a significant positive association between coffee consumption and increased risk of coronary heart disease. The authors reported a 21/2 fold increased risk among those drinking 5 or more cups of coffee daily, with a 95% CI from 1.08 to 5.77. Based on these data, PH office recommended people limit their coffee drinking to 2 cups or less per day. On what basis do you agree or disagree with this recommendation?

Donating Blood to Grandma?Can young blood help old brains? Several studies1 in mice indicate that it might. In the studies, old mice (equivalent to about a 70-year-old person) were randomly assigned to receive blood plasma either from a young mouse (equivalent to about a 25-year-old person) or another old mouse. The mice receiving the young blood showed multiple signs of a reversal of brain aging. One of the studies2 measured exercise endurance using maximum treadmill runtime in a 90-minute window. The number of minutes of runtime are given in the table below for the 17 mice receiving plasma from young mice and the 13 mice receiving plasma from old mice. The data are also available in YoungBlood.

23.2 Aerosolized Vaccine for Measles. An aerosolized vaccine for measles wwas (pages 530 and 532). process developed in Mexico and has been used on more than 4 million children since 1980, Aerosolized vaccines have the advantages of being able to be administered by people without clinical training and do not cause injection-associated infec tions. Despite these advantages, data about efficacy of the aerosolized vaccines against measles compared to subcutaneously injection of the vaccine have been inconsistent. Because of this, a large randomized controlled study was conducted using children in India. The primary outcome was an immune response to measles measured 91 days after the treatments. Among the 785 children receiving the sub- cutaneous injection, 743 developed an immune response, while among the 775 children receiving the aerosolized vaccine, 662 developed an immune response. (a) Compute the proportion of subjects experiencing the primary outcome for both the aerosol and…

Calcium is the most abundant mineral in the human body and has several important functions. Most of the body calcium is stored in the bones and teeth, where it functions to support their structure. Recommendations for calcium are provided in Dietary Reference Intakes, developed by the Institute of Medicine of the National Academy of Sciences. The recommended adequate intake (RAI) for calcium for adults (ages 19-50) is 1000 mg per day. A random sample of 18 adults with incomes below the poverty level gave the following calcium intakes:886 633 943 847 934 8411193 820 774 834 1050 10581192 975 1313 872 1079 809Assume the population standard deviation for daily calcium intake for adults with incomes below the poverty level is 188mg.At the 0.05 level of significance, does the data provided above provide evidence to suggest that the mean calcium intake of all adults with incomes below the poverty level is less than the RAI pf 1000mg per day?
