If I am creating my own experiment and my hypothesis states "socioeconomic status effects childhood obesity", What would be my independent and dependent variable?
For the data shown here, use the 0.01 level of significance in drawing conclusions from this experiment. Determine the 95% confidence interval for the population mean for each factor level.
1. Let X have a Poisson distribution with parameter 0. Assume that the unknown O is a value of a random variable 0 that has a gamma distribution with parameters IX = r and fJ = (1 -p)/ p, where r is a positive integer and 0 p 1.
