Question
Indicate in the following examples whether the random variable X is discrete of continuous. X is the number of days last week that a randomly chosen child exercised for at least one hour.__ X is the amount of time in hours that a randomly chosen child spends watching television today.__ For the following Histogram, calculate the following: 1st Quartile class: __ 2nd Quartile Class:__ 3^rd Quartile class:__ x axis variable:____ y axis Variable:__ Shape:_____ Approximate total number of frequencies (plants):_____ Spread of the Data:__Explanation / Answer
We will use the histogram to answer the question:
1st Quartile class - 10to20
2nd Quartile class - 20to30
3rd Quartile class - 30to50
x axis variable - number of seeds
y axis variable - number of plants
Shape - right skewed
Approx. total no. of freq = 2+12+13+4+7+4+1+1+3+1=48
Spread of data -> Range = 100-0=0, max=100,min=0, mode = 25,median=25
