rage adult Americans are about one inch taller, but nearly a whopping 25 pounds heavier than they ere in 1960, according to a new report from the Centers for Disease Control and Prevention (CDC). The bad news, says CDC is that average BMI (body mass index, a weight-for-height formula used to measure obesity) has increased among adults..." Boston is considered one of America's healthiest cities – is the weight gain since 1960 similar in Boston? A sample of n=28 adults suggested a mean increase of 19.5 pounds over the mean recorded in 1960 with a standard deviation of 8.6 pounds. Is Boston statistically significantly different in terms of weight gain from the national mean since 1960? Run the appropriate test at a 5% level of significance. Please use the five steps to demonstrate proper hypothesis testing and explain your results.

Are the digits of your R-number a quantitative or qualitative variable?
A poll was conducted on a representative sample of 600 adults living in the United States in order to investigate the decline in cable and satellite TV subscriptions. For this sample, 150 adults revealed that they are "cord cutters," (that is, they canceled their cable/satellite TV service and now only use a video streaming service). You want to estimate p, the true proportion of all US adults who are "cord cutters." Complete parts a through e. d. Give a practical interpretation of the confidence interval from part c. (Type integers or decimals rounded to three decimal places as needed. Use ascending order.) A. The probability that the true proportion of all US adults who are "cord cutters" is enter your response here lies between enter your response here and enter your response here. B. We can be enter your response here% confident that the true proportion of all US adults who are "cord cutters" lies between enter your response here and enter your…

Joshua went to a doctor's appointment yesterday. He was weighed and the paperwork said that his weight put him in the 35th percentile for weight. This means that for all [gender] that were weighed at the same [age], [per]% of them weighed [compare] Joshua.

Researchers often rely on surveys to capture a subjective assessment of well-being. One study finds that holding everything else constant, people seem to be least happy when they are in their 40's. Another study suggests that money does buy happiness, but its effects diminishes as income rises above $75000 a year. The accompanying data file includes survey daa of 100 working adults' self-assessed happiness on a scale of ) to 100, along with their age and annual income. Estimate and interpret a regression model based on Age, Age 2 and income. Predict happiness with income equal = to $80000 and age equal to 30, 45, and 60 Years Predict happiness with Age equal = to 60 and income equal to 25,000, 75000, and 125000 Happiness Age Income 69 49 52000 83 47 123000 86 72 112000 73 52 166000 89 68 90000 81 37 152000 75 48 58000 56 48 50000 75 56 93000 57 51 27000 77 60 173000 83 55 173000 85 75 68000 82 69 157000 63 39 40000 70 66 107000 78 34 109000 53…
According to the CDC, cholesterol levels can be reduced by following a healthy diet, getting regular exercise, and reducing the amount of alcohol consumed on a weekly basis. One method of monitoring overall cholesterol levels is to calculate your cholesterol ratio (LDL/HDL), in general a cholesterol ratio between 3.5 and 5.0 is considered to be healthy for most adults. Suppose you are a clinical researcher testing the effects of these lifestyle changes on patient cholesterol levels. In order to determine if following these guidelines helps to reduce overall cholesterol, a total of 18 participants (N = 18) with moderate to high cholesterol ratios (i.e., 3.91 to > 5.0) were recruited for a healthy lifestyle study and their cholesterol ratio was calculated three times over a six week period: Week 0 (baseline), Week 3, and Week 6. Using the variables "Week 0", "Week 3", and "Week 6" in the data set, conduct a One-Way, Within Subjects (AKA Repeated Measures) ANOVA, at α = 0.05, to see…

. Students may be classified as having a math dysfunction—and not have to take statistics—if they score below the 25th percentile on a diagnostic test. The m of the test is 75 and sX 10. Approximately what raw score is the cutoff score needed to avoid taking statistics?
