The original data set is in the picture and the question parts needs to be answered as well for the original data set. Read and answer carefully and correctly. Compute the mean, median, and mode for the data. Show your complete work. (b) Compute a 5% trimmed mean for the data, and compare it with the mean computed in part (a). Does the trimmed mean more accurately reflect the general level of the daily rental costs? If 5 will be added to each cost of condominiums, what will be the mean, median and mode? If each cost of condominium will be added by 10 and multiplied by 2, what will be the mean, median and mode?

You may need to use the appropriate appendix table or technology to answer this question. Older people often have a hard time finding work. A research group reported on the number of weeks it takes a worker aged 55 plus to find a job. The data on number of weeks spent searching for a job is given in the table below. (a) Provide a point estimate of the population mean number of weeks it takes a worker aged 55 plus to find a job. ———Weeks (b) At 95% confidence, what is the margin of error? (Round your answer to four decimal places.) ———Weeks (c) What is the 95% confidence interval estimate of the mean? (Round your answers to two decimal places.) ————-Weeks to ————- weeks.

Monthly salary computations from two different companies yielded the following data: n1 = 7, x1=9,120$, s1=384$; n2 = 7, x2=8,820$, s2=214$. At the level of significance 0.05, can we conclude that the mean monthly salary from the two ompanies is not the same?
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…
