Answer all plz Match the summary statistics with the histograms. Hint: there isn't enough detail to compute the mean, median and standard deviation, but you can a about the relationship between the mean and the median when the graph is skewed, and when is s in the x-axis and thinking which one has a larger standard deviation. a. mean = 4.99, median = 3.13, standard deviation-5.49 b, mean = 4.89, median = 4.83, standard deviation = 7.99 c. mean = 5.01 , median = 6.87, standard deviation = 5.49 d, mean = 4.96, median = 4.93, standard deviation = 0.96 Variable-13 Variable-2 Variable- Variable-F 250 + 150+ 100 50 150 T -22 2 8 18 variable 2 1.5 4.5 7.5 variable 1 300 T 200 100 400 300 200 100 0.0 18.0 36.0 -36 -16 4 variable 3 variable 4

Explanation / Answer

a) positive ly skewed so varible 3 is the right answer

in casae of b and and d they are symetric but sd of 2 is more than sd of 1 clear from histograms so for b) variable 2 and for d) variable 1 is appropriate ..and for c) it is the feature of negatively skewed distribution so variable 4 is appropriate

b) it is observational prospective study as the researcher identified 50 puppies (cohort,without thyroid) and observing them for several years that is it is a longitudinal cohort study and he checks the diet how it affect the thyroid problem ...I mean he wants to determine how it these factors affect the tyroid problem

c) I think 1 and 2 both are correct ...as 1/3 of the surveyers returned with 44% they found of lower price that means they are potential car buyers on the other hand 2/3 of total surveyrs returned with non response so both are correct ..
