It has been noted that the amount of time people spend shopping in supermarkets incountry X has decreased due to the discovery of a new strain of Covid 19. Based onthis realization, the manager of Power Supermarket decided to collect data for thelength of time people spend in his supermarket during a one week period. He is aimingto use the data to help him decide if the supermarket should be converted to a virtualsupermarket/a delivery based one.a. Use the information below to construct two frequency polygons.b. Do you think that Power Supermarket should close their doors? Explain your answer.*Assume that a person who spends more time in a supermarket buys a lot of goods anda person who spends a short time in a supermarket, buys few goods.Before the pandemic:After the pandemic:TimeTimeFrequencyFrequency1-5501-5306-10256-106511-152211-154516-208016-205021-256021-253526-304526-304031-353531-3535

6. Fill in the missing values in the following table of relative frequency, labelled A- J. Show how you calculate each value, and put your final answer for each value in the table below (e.g., replace "A" with your found value). The method you use can be different from mine, but you must show how you arrive at each value. Hint: go in order. Find A, then B, etc. Tutorial video 3 should be very helpful here.

Suppose a researcher collects data on the air pollution levels, measured in milligrams per cubic meter, for both urban and rural areas in 35 states. The data is plotted with urban air pollution levels on the horizontal axis and rural air pollution levels on the vertical axis. Nevada is an outlier in the ?x‑direction. What must be true about this state? The urban air pollution levels for this state are much higher or lower than the rest of the states in the data set. The rural air pollution levels for this state are much higher or much lower than the rest of the states in the data set. This state is an influential observation. The rural air pollution levels for this state are much higher or lower than other states in the data set that have similar urban air pollution levels. The absolute value of the residual of this state is large.

Consider the women's 100-yd dash (and the subsequent 100-m dash) in the Olympics since records have been kept. Determine the best way to combine all data and depict the data. Choose the correct answer below. O A. A line graph would be the best way to show all of the data over time, but some measurements would have to be converted to display the 100-yd and 100-m on the same graph. OB. A scatterplot would show the relationship between the 100-yd dash and the 100-m dash. O C. A stem and leaf plot would be the best way to show all of the data grouped by race times. O D. A histogram would show all of the data by comparing each year. The units of distance would not matter.
