In the histogram, it is clear that the distribution is uniform. C. In the histogram, the trend over time is clear b) What features can you see in the time series plot that aren't clear in the histogram? O A. In the time series plot, it is clear that the distribution is left skewed. O B. 0 D. In the histogram, it is clear that the distribution is bimodal. In the histogram, it is clear that the distribution is left skewed. B. O C. 0 D. In the time series plot, it is clear that the distribution is bimodal. In the time series plot, it is clear that there is no strong trend or change in variability. In the time series plot, the trend over time is clear. c) Which graphical display seems more appropriate for these data? Explain. OA. 0 B. OC. O D. Since there is a strong trend over time, the histogram is more appropriate. Since there is a strong trend over time, the time series plot is more appropriate Since the distribution is symmetric, the histogram is more appropriate Since the distribution is bimodal, the time series plot is more appropriate. d) Write a brief description of unemployment rates over this time period in the country. The unemployment rate I steadily from at the beginning of 1995 to | at the end of 1996 and then steadily from the beginning of 1997 to |atthe end of 1997Explanation / Answer

c) OPTION B
Time series plot seemsto be more appropriate for these data. Time series plot is used to study patterns of a numerical value over time. Teh time series plot clearly shows the rate of unemployment at different years.
d) The unemployment rate DECREASES steadily from over 6% at the beginning of 1995 to about 4% at the end of 1996 and then INCREASES steadily from the beginning of 1997 to over 5% at the end of 1997
