Explanation & Answer
The metric system is a system of measuring. It has three main units:
m | the meter for length |
kg | the kilogram for mass |
s | the second for time |
Example..if you get 12 cm, divide by 100 to get 0.12 meters as the metric measurement.
I hope you understand.

PUBH8545 Medical Exploration Screening for Cardiovascular Disease Report
In many different situations, you may be exposed to information that requires further analysis; this may be true as you receive reports, read a journal, or prepare for a presentation. What is certain is that you should always approach results in a critical but unbiased way, and be prepared to address any potential weaknesses in the reported data.For this Discussion, you will evaluate recommendations made based on the results of a study from a given scenario.To prepare:Select one of the following scenarios:Scenario 1: A sample of 5,000 swimmers and 5,000 runners were screened for cardiovascular disease (CVD). The study found that the rate of CVD is 33.3% in swimmers and 30.9% in runners, with the p-value of <0.05. A public campaign is recommended to promote running instead of swimming activities.Scenario 2: A study of 1,000 married women was conducted concerning pre-marital birth and the success of the subsequent marriages. The study reported that less educated women were 30% more likely to have children before marriage than highly educated women. In addition, 40% of the African-American women in the study had children before marriage. The study concluded that marriage counseling should be provided to less educated women and to African-American women.Post an evaluation of the recommendation from your scenario. Include the following in your post:The scenario number you selectedYour evaluation of whether the recommendations are overstated or understated based on the results described in the scenario (justify your response)Your suggestion of two methods for addressing and correcting those errorsSupport your post with the Learning Resources and current literature. Use APA formatting for your Discussion and to cite your resources.Referenceshttps://class.waldenu.edu/bbcswebdav/institution/USW1/201950_27/PH_PUBH/PUBH_8545_WC/readings/USW1_PUBH_8545_Week10_wantedValidAndMeaningfulData.pdfFullerton, S.

It is noted in CCBC’s student information system that you are a student that needs to complete their first attempt at math placement with CCBC’s math assessment test, ALEKS. The purpose of this communication is to provide you with access and directions to complete the 1st attempt. ALEKS Math Assessment The ALEKS Math Assessment ensures students' readiness for certain math and science- based courses at CCBC. Since these courses are demanding, it is important for you to start with a firm foundation in your understanding. What you need Uninterrupted work time (plan for two hours) A pencil and paper A reliable Internet Connection If you have a technology issue, please reply to this email. New User to ALEKS notices Before you take the assessment, ALEKS will present a short tutorial on how to enter answers, how to use the graphing utilities, and how to use the built-in calculator. TAKE YOUR TIME WITH THIS TUTORIAL. The ALEKS assessment has up to 30 questions depending on your progress. Plan to complete the assessment in a single one- to two-hour sitting. However, you can stop and restart but you will have 24 hours to complete the assessment once you start. Once started, if you do not finish within 24 hours, the assessment is reset.

Walden University 7 Quantitative Null Hypothesis Correlation Quiz Discussion
Please answer at least 5 out of 7 correctly on this multiple choice quizA common convention in social science is to set the alpha level at .05 and to reject the null hypothesis if the observed significance level is less than the alpha level, p < .05. Which of the following is correct?a.If p = .041, do not reject the null hypothesis b.If p = .074, reject the null hypothesis c.If p = .000, reject the null hypothesisd.If p = .952, reject the null hypothesis14.29 points QUESTION 2A Type I error is when you incorrectly reject the null hypothesis of no difference or no correlation in a population based on the results found in a sample. The alpha level controls the rate of Type I errors. If alpha is set at .05, which of the following is correct?a.The probability that there is no difference or no correlation in the population is 5%.b.The probability that there is a difference or correlation in the population is 5%. c.The probability of incorrectly rejecting the null hypothesis from the results of a sample, if the null hypothesis in the population is true, is 5%.d.The probability of correctly rejecting the null hypothesis from the results of a sample, if the null hypothesis in the population is true, is 5%.14.285 points QUESTION 3A confidence interval is a range of population values estimated from the results of a sample. From a random sample of 100 graduate students at Walden, suppose you calculate the average age to be 37 plus or minus 11, which would make the lower limit of the confidence interval 26 (i.e., 37 – 11 = 26) and the upper limit 48 (i.e., 37 + 11 = 48). If this was a 95% confidence interval, which of the following is correct?a.There is a 5% probability that the true average age of Walden graduate students is between 26 and 48b.95% of all Walden graduate students are between 26 and 48 years of agec.The true average age of Walden graduate students could be less than 26 or greater than 48d.A 99% confidence interval would be narrower, for example between 32 and 4214.285 points QUESTION 4A 95% confidence interval of -1.34 to 2.56 was estimated from the sample data on the mean difference between males and females on statistics anxiety. Which of the following is a true statement?a.The mean difference between males and females is statistically significantly different at the .05 alpha levelb.The mean difference between males and females is NOT statistically significantly different at the .05 alpha level c.95% of all male and female scores on statistics anxiety were between -1.34 to 2.56d.The power of the study was 5%14.285 points QUESTION 5Incorrectly accepting the null hypothesis of no difference or no correlation in a population based on the results found in a sample is… a.a Type I errorb.a Type II errorc.a Type III errord.a Type IV error14.285 points QUESTION 6Scenario:A purposive sample of psychology graduate students finishing up their dissertation at one online university (n = 80), one public brick-and-mortar university (n = 35), and one private brick-and-mortar university (n = 20) rated overall satisfaction with their dissertation chair using a scale of 0 (completely dissatisfied) to 100 (completely satisfied). Each university had 100 students finishing up their dissertation. The mean satisfaction ratings were: online = 87.5, public brick-and-mortar = 82.7, private brick-and-mortar = 90.3. The standard deviations were equal. Which of the following pairwise comparisons of mean ratings would have the largest effect size?a.Public versus privateb.Public versus onlinec.Online versus privated.The effect size of each pairwise comparison would be equal14.285 points QUESTION 7If an independent samples t test was conducted between any two of the three types of universities, which of the following would be most appropriate effect size?a.Multiple-R2b.Cohen’s wc.Cohen’s dd.Likelihood ratio

sample size of population
In a certain population, body weights are normally distributed with a mean of 152 pounds and a standard deviation of 26 pounds. How many people must be surveyed if we want to estimate the percentage who weigh more than 180 pounds? Assume that we want 96% confidence that the error is no more than 2.5 percentage points.
