Dr.Blume has trained observers to use frequency recording to record the behavior of 12 schizophrenic clients. According to the analysis of the data κ = 0 . 47, do you think the observers are sufficiently trained to allow Dr. Blume to proceed with the research?
The table available below shows the weights (in pounds) for a sample of vacuum cleaners. The weights are classified according to vacuum cleaner type. At a = 0.10, can you conclude that at least one mean vacuum cleaner weight is different from the others? Click the icon to view the vacuum cleaner weight data.

The following histograms represent the heights, measured to the nearest cm, of 14 women and 13 men. Women's heights 3- 2- 1 150 155 160 165 170 175 180 185 190 Height (cm) Men's heights 2 1 0+ 150 155 160 165 170 175 180 185 190 Height (cm) Choose the two options from the list below that are true. Select one or more: Each of the intervals with the lowest frequency in the women's heights dataset contains a smaller number of data values than one of the intervals with the lowest frequency in the men's heights dataset. The histograms are divided into six intervals for the women's heights dataset and eight for the men's heights dataset. The histogram of the women's heights dataset has a greater number of intervals containing two values than the histogram of the men's heights dataset. Both histograms are right-skewed. O The range of the women's heights dataset is greater than the range of the men's heights dataset. Aouan ba Aouan ba
If we multiply the data values by a constant (say, c), how this will affect the geometric mean? Use the equation in image to prove it, and give an example.
