ings Review View Help 12. The city council is considering a law that would ban smoking in all public facilities. A sample has been selected from the community and tested for support of the ordinance. Is there a statistically significant relationship between age and support for the anti-smoking law? Use the five step model as a guide and write a sentence or two interpreting your results. Age More than 40 78 169 247 Less than 40 Support: For Against 145 103 248 223 272 495 A. Use probabilities to determine if these two variable are independent or dependent P(Less than 40) = P(Less than 40 |For) = P (Less than 40 | Against) = Are age and support for the anti-smoking law independent? (Yes = independent / No = not independent) B. Conduct a hypothesis test using an alpha of .05 that these variables are i ndependent versus the alternative that they are related. a. Step 1: State Hypotheses H: H: b. Step 1-1: Construct expected frequency f.= (RM CM)
age adult Americans are about one inch taller, but nearly a whopping 25 pounds heavier than they were in 1960, according to a new report from the Centers for Disease Control and Prevention (CDC). The cad 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 n328 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.
Following this week's empirical application, the scatter plot below plots average rain in a city (vertical axis) against average PM 10 levels in a city (horizontal axis). Based on this figure, what appears to be true? Average Rain in a City u Rain vs Pollution by City 120 Average PM10 in a City 160 Cities with more rain tend to have less pollution O Cities with less pollution tend to have less rain O There is no statistical relationship between rain and pollution O Cities with more rain tend to have more pollution
