Mean - find the sum of that set of numbers then divide your answer by the total of numbers in the set. E.g if the numbers are 10, after finding the sum you divide it by 10 since the numbers are ten.
Median - first arrange the numbers from small to big than find the middle number and if they are two like when the numbers are of an even number than you add the two numbers and divide answer by 2.
Range - arrange the numbers from small to big than minus the smallest one from the biggest number.
Am not sure about the last one but I hope I was able to help you with this three.
I believe it is 4 because 12/3=4
Answer:
The 95% confidence interval for the true proportion of households which rely strictly on cell phones for their phone serviceis (0.2453, 0.3947).
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of 
, and a confidence level of 
, we have the following confidence interval of proportions.
In which
z is the zscore that has a pvalue of 
.
A random sample of 150 households was selected and 48 relied strictly on cell phones for their service.
This means that 
95% confidence level
So 
, z is the value of Z that has a pvalue of 
, so 
.
The lower limit of this interval is:
The upper limit of this interval is:
The 95% confidence interval for the true proportion of households which rely strictly on cell phones for their phone serviceis (0.2453, 0.3947).
Answer:
btw the mode is the biggest number there, the median is the difference of the smallest and biggest, range is the smallest number, and mean is the number of numbers
Step-by-step explanation:

She will most likely round to 40 since 37 is closet to that
