C- Scatter Plot
Step-by-step explanation:
For the first one, 1 1/2 + 1 1/2 = 3

That leaves us with the missing number.
Same with the rest of them, subtract the number that is know from the total.
#3 is 2 1/2

Answer:
Standardized z score = 2.06
His house rent is not an outlier
Step-by-step explanation:
The mean monthly rent of students at Oxnard university is 970 with a standard deviation of 204. John`s rent is 1390. What is his standardized z-score? Is john`s rent an outlier? How high would the rent have to be to qualify as an outlier
We solve using z score formula
= z = (x-μ)/σ, where
x is the raw score = 1390
μ is the population mean = 970
σ is the population standard deviation = 204
His z score is calculated as:
z = 1390 - 970/204
z = 2.06
No his house rent is not an outlier
