Measured Amounts of arsenic from independent samples of the same size of brown rice can be found in Arsenic in rice. All measurements are in micrograms per serving and the data is from the food and drug administration. each sample appears to be from a population having a normal distribution. use a 0.05 significance to test the claim that the mean amount of arsenic in rice is the same in california, arkansas, and texas.

3. The following results come from two independent random samples taken from two populations. Sample Size Sample Mean Population Standard Deviation Sample 1 n1=52 x1=15.4 σ1=3.1 Sample 2 n2=64 x2=17.3 σ2=4.2 Provide a 95% confidence interval for the difference between two population means. Using the critical value approach, test whether the population means differ at the 5% significance level. Using the p-value approach, test whether the population means differ at the 5% significance level.

1a. Consider two samples from the same population. Sample A has size n=500 and Sample B has size n = 200. Indicate whether each of the following statements is true or false. We would expect Sample A to have a larger mean than Sample B. We would expect the mean of Sample A will be closer to the population mean than the mean of Sample B. We would expect the 95% confidence interval (CI) based on Sample A will have...
