Suppose that a histogram is constructed for the frequency distribution shown below. Does the distribution appear to be normal? Why or why not?ONo, the distribution is not normal because the values are not concentrated in the center and do not taperoff symmetrically towards the ends.Yes, the distribution is normal because the values are concentrated in the center and taper offsymmetrically towards the ends.Yes, the distribution is normal because the values are evenly distributed.No, the distribution is not normal because the values are evenly distributed Age Frequency30-3940-4950-5960-6919126

Based on the scatter plot, determine whether each of the following statements is TRUE or FALSE no explanaition is needed: Older DDS recipients generally had higher annual DDS expenditures The histogram of annual DDS expenditures would be unimodal. The median annual DDS expenditures of these DDS recipients would be higher than their mean annual DDS expenditures.
Often, frequency distributions are reported using unequal class widths because the frequencies of some groups would otherwise be small or very large.

Resting Pulse: earlier this semester we determined our resting pulse. Seventy-nine individuals participated in this data collection. The mean heart rate for all individuals was 65.34 beats per minute. A random sample of 30 heart rates having a mean of 64.97 beats per minute is presented here. Build a frequency table of these data containing six (6) classes with the lower llimit of the second class at 54 beats per minute. Build a chart appropriate for the presentation of these data.
