2. A test has a maximum possible score of 200. The results achieved by a class of 20 students are listed: 168, 152, 112, 88, 95, 123, 177, 166, 145, 104, 112, 156, 110, 141, 177, 166, 134, 190, 111, and 120. a) Determine the mean, median, and mode. b) What are the quartiles for this data set? c) Jacquelin's mark is in the 40th percentile for this group. Explain what the percentile means. What is Jacquelin's mark? (4

The personnel files of all eight employees at the Pawnee location of Acme Carpet Cleaners Inc. revealed that during the last 6-month period they lost the following number of days due to illness: 5 5 4 4 1 2 All eight employees during the same period at the Chickpee location of Acme Carpets revealed they lost the following number of days due to illness: Range Mean 2 1 0 10 2 2 3 0 0 6 Click here for the Excel Data File Required: a. Calculate the range and mean for the Pawnee location and the Chickpee location. (Round the "Mean" to 2 decimal places.) Pawnee location O Chickpee location O Pawnee location Chickpee location b-1. Based on the data which location has fewer lost days?

The questions below are based on a dataset containing the characteristics of 5,407households. In particular, we will use the following variables:- size: home size, measured in square feet.- hhinc: annual household net income, measured in euros.- owner: dummy variable equal to 1 if the living space is owned, and 0 if the livingspace is rented.- hhsize1: dummy variable equal to 1 if the number of household’s members is 1 or2, and 0 otherwise.- hhsize2: dummy variable equal to 1 if the number of household’s members is 3 or4, and 0 otherwise.- hhsize3: dummy variable equal to 1 if the number of household’s members is 5 orabove 5, and 0 otherwise.- edu: education level of household’s members. We conduct a simple regression of size on hhinc, now using robust standard errors.The regression output is reported in Table 2. Why are the estimated coefficients inTable 2 equal to the estimated coefficients in Table 1? Do the conclusions on thestatistical significance at 5% of the coefficient of…
