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 1653 18 1916 18 14 50 2 29 1934 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.) 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? A histogram of the data shows the distribution is perfectly symmetric. One might suggest collecting a larger sample, at least 50, in the future. A histogram of the data shows some evidence that the distribution may be skewed to the right. One might suggest collecting a larger sample, at least 50, in the future. O A histogram of the data shows some evidence that the distribution may be skewed to the right. One might suggest collecting a smaller sample, at most 15, in the future.
