Determine the cumulative deviations and the backlog for each period.

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?

Suppose researchers at an abdominal transplant clinic are concerned about the rate of graft loss due to diabetes status prior to receiving a donor kidney. Research has shown that gender discordance, or receiving a gender from a donor of an opposite gender may increase the risk of both exposure and outcome after transplant. Assume the following tables represent the stratified analysis of the potential confounding variable. (9 points)   Gender Discordance Graft Failure No Graft Failure Total Diabetes II 23 10 33 No Diabetes II 4 44 48 Total 27 54 81 Gender Concordance Graft Failure No Graft Failure Total Diabetes II 9 34 43 No Diabetes II 12 87 99 Total 21 121 142   A)  Calculate the stratum specific estimates for the odds ratios in each strata. B)  Observe the difference in the odds ratios. Based on observation alone, what are we likely to conclude regarding the relationship between outcome and exposure…

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. 23 16 53 18 19 16 18 14 50 2 29 19 34 26 14 12 54 23 28 16 15 26 21 30 28 28 12 23 46 38 24 41 19 19 12 21 18 24 7 24 (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.) X weeks (c) What is the 95% confidence interval estimate of the mean? (Round your answers to two decimal places.) weeks to weeks (d) Discuss the degree of skewness found in the sample data. What suggestion would you make for a repeat of this study? O A histogram of the data shows the distribution is perfectly symmetric. One might suggest collecting a larger sample, at least 50, in the future. O A histogram of the data shows some…
