1.34 Means and SDs. For each part, compare distributions (1) and (2) based on their means and standard deviations. You do not need to calculate these statistics; simply state how the means and the standard deviations compare. Make sure to explain your reasoning. Hint: It may be useful to sketch dot plots of the distributions. (a) (1)3,5,5,5,8,11,11,11,13 (2) 3, 5, 5, 5, 8, 11, 11, 11, 20 (b) (1) -20, 0, 0, 0, 15, 25, 30, 30 (2) -40, 0, 0, 0, 15, 25, 30, 30 (c) (1)0,2,4,6,8,10 (2) 20, 22, 24, 26, 28, 30 (d) (1) 100, 200, 300, 400, 500 (2) 0, 50, 300, 550, 600

Now, martin can reasonably guess that the standard deviation for the entire population of people at the mall during the time of the survey is $1.50. what is the 95% confidence interval about the sample mean? interpret what this means in the context of the situation where 95 people were surveyed and the sample mean is $8. use the information in this resource to construct the confidence interval.
