Variability is the measure of the variation of a data set from the center. The mean and the median are the qualities that measure the center of a distribution.
For the first option, if more data is clustered around the median, (the measure of center), then the distribution has less variability than when less data is clustered around the median. Therefore, the first answer option is not correct because if more data is clustered around the median in the shaded plants set, then the shaded plant set will have less variability.
For the second option, the range is a measure of variability which measures the spread of the data set from the least value to the greatest value, but it does not take into account the variability of the other data values of the data set. Thus the range is regarded as a weak measure of variability and is not used when other measures of variability are available. Therefore, the second option is not correct.
For the third option, the inter-quartile range (IQR) is a better measure of variability than the range because it takes into account more data points than the range. Now, because, the f<span>ull sun plants set has a greater IQR, this shows that they have greater variability. Therefore, the third option is the correct answer.
For the fourth option, the median is not a measure of variability. Thus, that a data set has a greater median than another data set does not mean that the data set would have a greater variability. Therefore, the fourth option is not the correct answer.</span>

Step-by-step explanation:
Add up the ratios and divide 48 by 6(added up ratios) and you get 8. Multiply that by individual ratios.
Answer:
Following are the responses to the given choices:
Step-by-step explanation:
In step 1:
State the zero and alternate test hypotheses. Insert underneath.
Smaller companies in their region are and they spend at least 24 hours per week on the marketing of the these companies
There really is no growth for smaller firms in their area because the companies spend or less 24 hours per week on marketing.
In step 2:
Each test statistics meaning is calculated. Around two decimal places for your reply.
In step 3:
Draw a start and write the decision.
Since it is observed that 
it is then concluded that the null hypothesis is rejected.
Consequently we consider that small companies in their field may not expand, as they spend or less 24 hours per week on marketing.
Answer: y = 1/4x
Step-by-step explanation:
If the constant of proportionality is K, then:
y = kr
In which equation do we multiply x by 0.25 to get y?
1/4 = 0.25
Answer:
It will cost: £28.28
Step-by-step explanation:
Area of sphere = 4 x π x r2
Area of Circle = 4 x π x 3^2 = 113.097 (radius is half of diameter)
113.097 / 0.25 = 28.28
