Construct a scatter diagram and interpret.
Bicycle helmet use. Table1lists data from a cross-sectional survey of bicycle safety. The explanatory variable is a measure of neighborhood socioeconomic status (variable RFM). The response variable is "percent of bicycle riders wearing a helmet" (P Helm).
Percent of school children receiving free or reduced-fee lunches at school (variable P_RFM) and percent of bicycle riders wearing a helmet (variable P_HELM). Data for this study was recorded by field observers in October of 1994.I (i) School P_RFM P-HELM 1 Fair Oaks 50 22.12 Strandwood 11 35.93 Walnut Acres 2 57.94 Disc Bay 19 22.25 Belshaw 26 42.46 Kennedy 73 5.87 Cassell 81 3.68 Miner 51 21.49 Sedgewick 11 55.210 Sakamoto 2 33.311 Toyon 19 32.412 Lietz 25 38.413 Los Arboles 84 46.6
Construct a scatterlpot of P_RFM and P_HELM. If drawing the plot by hand, use graph paper to ensure accuracy. Make sure you label the axes. After you have constructed the scatterplot, consider its form and direction. Identify outliers, if any.
Determine the mean number of times the machine was used per day.
Use a 5% significance level to test the claim that there appears to be a difference in the effectiveness of the two diets.
What should the cut-off score be for the interviews? (Round to nearest whole number).
Using the dataset, produce a graph of per capita GDP for Argentina, China, and Canada from 1965 to 1995. Is inequality between these countries increasing?
The mean of a sample is 22.5. The mean of 1000 bootstrapped samples is 22.491. The bias of the bootstrap mean is
Below are the sample times in minutes. At the .05 significance level, can we conclude that there is a difference in their mean times?
Which of the following is true about the expected value of perfect information. It is the amount you would pay for any sample study.
Assume that the smiling time of eight-week old babies, in seconds, follows a uniform distribution between 0 and 23 seconds, inclusive. This means that any smiling time from 0 to and including 23 seconds is equally likely.
Conduct post hoc comparisons with the LSD method. Which groups differ significantly at α = 0.05?
To test whether the population standard deviation differ significantly using Chi-Square test.
Find the sample size for the 95% confidence interval used to estimate the population proportion.
Categorize the events as dependent or independent. Events A and B where P (A) = 0.7, P (B) = 0.8, and P (A and B) = 0.56.
