(a) For these data, which measures of central tendency take more than one value? Choose all that apply. Median OMode ONone of these measures (b) Suppose that the measurement 238 (the OMean largest measurement in the data set) were replaced by 351. Which measures of central tendency would be affected by the change? Choose all that apply. O Median OMode None of these measures OMean (c) Suppose that, starting with the original data set, the largest measurement were removed. Which measures of central tendency would be changed from those of the original data set? Choose all that apply. OMedian OMode ONone of these measures

Suppose the observational units in a study are the patients arriving at an emergency room on a given day, Nov 11, 2019.  Number of patients that arrive before noon     is a qualitative variable       is a quantitative variable       is not a variable

Which of the following is a characteristic of quantitative data? A It focuses on subjective interpretations and opinions B It is collected through interviews and focus groups. C It can be easily represented using graphs and charts D) All of the above

The full question didn't fit in one part so I attached 2 photos.

I'm looking for help on the first 3 bullet points please.

1) The question screenshot attached down below answer all and just need final answer

The problem below asks you to compare 4 different forecasting methodologies to determine which forecasting model results in the most accurate forecasts.  Accuracy is determined by the lowest mean absolute deviation.   Emergency calls to the 911 system of Greenville County for the past 24 weeks are shown below.  Accurate forecasts are needed to determine the number of operators needed to staff the station.    Week # of Calls 1 50 2 35 3 25 4 40 5 45 6 35 7 20 8 30 9 35 10 20 11 15 12 40 13 55 14 35 15 25 16 55 17 55 18 40 19 35 20 60 21 75 22 50 23 40 24 65     1. EXPONENTIAL SMOOTHING Compute the forecasts using α = .2.  Calculate the MAD for weeks 4 through 24 only. Compute the forecasts using α = .6.  Calculate the MAD for weeks 4 through 24 only.   2. SIMPLE LINEAR REGRESSION Use all of the data, weeks 1 - 24, to calculate the…

Sections a and b please

14. The range is defined as the: a. variability of the data with reference to extreme scores. b. the variability of the data with reference to the mean. c. variability of the data in terms of how many subjects achieved each value of the variable. d. SS/n

Lecture(10.8): The Peabody Picture Vocabulary Test has a standard score mean of 100 and a standard deviation of 15. You tested a class of grade 2 students wonderinf if these scores would be different  from the population. After testing this hypotheses  you decided to continue looking at this data  to determine if there are any group differences based on birth order. You group the children the on whether  they are the oldest chlid, middle child, or the youngest child. Here is the data based on grouped information.   Oldest child:       87       84     98     104      106      91       96   92 Middle child:       65      74      62      60         73       64       71    78 Youngest child:   115     84      85     83        95        94     108   102    89 Test the hypotheses at (alpha=0.05) level of signifance using the 5 step procedure.Make sure to clearly state the null and alternative hypotheses.Round your answer to 2 decimal. You are encouraged to use the following table to help you…
