What is the difference between multivariate data set and bivariate data?

You conducted a study to assess the effect of smoking on systolic blood pressure. The results showed that there was a significant association between the two variables, with an odds ratio of 1.5. Explain this finding to someone who has no background in epidemiologic research.

Find a real-life example of the use of ANOVA (Make sure to cite the source). Explain how and why they used ANOVA.

Levi-Strauss Co manufactures clothing. The quality control department measures weekly values of different suppliers for the percentage difference of waste between the layout on the computer and the actual waste when the clothing is made (called run-up). The data is in the table, and there are some negative values because sometimes the supplier is able to layout the pattern better than the computer. Do the data show that there is a difference between some of the suppliers? Test at the 1% level. Run-ups for Different Plants Making Levi Strauss Clothing Difference Plant Plant 1 11.9 Plant 1 3.9 -10.6 Plant 1 Plant 1 Plant 1 Plant 1 Plant 1 Plant 1 Plant 1 Plant 1 Plant 1 Plant 1 Plant 1 Plant 1 Plant 1 Plant 1 Plant 1 Plant 1 Plant 1 Plant 1 Plant 1 Plant 1 Plant 2 Plant 2 Plant 2 Plant 2 Plant 2 Plant 2 Plant 2 Plant 2 Plant 2 Plant 2 Plant 2 Plant 2 Plant 2 Plant 2 Plant 2 Plant 2 Plant 2 Plant 2 Plant 2 Plant 2 Plant 2 Plant 2 Plant 3 Plant 3 Plant 3 Plant 3 Plant 3 Plant 3 Plant 3…

Suppose the value of a stock varies each day from $10.82 to $23.17 with a uniform distribution. Find the third quartile, i.e. , 75% of all days the stock is below what value ?

You are examining two data sets involving test scores, set A and set B. The score 96 appears in both data sets. In which of the following data sets does 96 represent a higher score? Explain.(a) The percentile rank of 96 is higher in set B than in set A. A. 96 represents a higher score in Set A because a larger percentage of scores fall below 96 in set A.B. 96 represents a higher score in Set B because a larger percentage of scores fall below 96 in set B. C. 96 represents an equivalent score in both sets because an equal percentage of scores fall below 96 in both sets.D. It is impossible to tell in which set 96 represents a higher score because a percentage depends on the number of test scores in the set, which is unknown. (b) The mean is 90 in both data sets, but set A has a higher standard deviation.A. 96 represents a higher score in Set A because 96 is more standard deviations above the mean.B. 96 represents a higher score in Set B because 96 is more standard deviations above the…
