The range is the simplest measure of variation . It is the difference between the biggest and smallest random variable.
Range= maximum value - minimum value
ex. Therefore in the range of these variables: (2,4,4,7} you would do 7 minus 2
Answer:
0.24315
Step-by-step explanation:
Using the z score formula to solve this question
z = (x - μ) / σ,
Such that:
x = raw score
μ = population mean
σ = population standard deviation.
From the question:
x = 3000
μ = 3550
σ = 870
z = (3000 - 3550) / 870
z = -550/870
z = -0.6962
Using the z score table as well as probability calculator(as requested in the question to find the z score)
The probability of having less than 3000 is obtained as:
P(x<3000) = 0.24315
Answer:
x=-1
Step-by-step explanation:
For this case we can make the following rule of three:
$ 10500 -------> 100%
$ 11300 -------> x
Clearing the value of x we have:
x = (11300/10500) * (100)
x = 107.6190476
The percentage of growth is:
107.6190476 - 100 = 7.6190476%
Round to the nearest tenth:
7.6%
Answer:
the percent increase in tution is:
7.6%
