Answer:
This can be solved by using the empirical rule for a normal distribution.
Step-by-step explanation:
A. The number of skateboards given is one standard deviation above the mean. Approximately 68% of the data points lie within the range plus and minus one standard deviation of the mean. Therefore the required percentage is:
68 + 16 = 84%.
B. The given number of skateboards is two standard deviations above the mean. Approximately 95% of the data points lie within the range plus and minus two standard deviations of the mean. Therefore the required percentage is:
5/2 = 2.5%
C.The given number of skateboards is one standard deviations below the mean. Therefore the required percentage is:
16%.
Answer:
Letty has 75%
Step-by-step explanation:
15/20 is the same as 75/100 ( 15/20·5) so she has a 75% grade
Answer:
Check the explanation
Step-by-step explanation:
Scatter plot
x---square feet
y---rent
SolutionA:
Kindly check the attached image below:
THERE EXISTS A WEAK POSITIVE RELATIONSHIP BETWEEN SQUARE FEET AND RENT .
AS SQUARE FEET INCREASES RENT INCREASES
SolutionB:
Rent=0.4932(squarefeet)+992.99
slope=m=0.4932
Y intercept=992.99
SolutionC:
Interpretation of slope:
slope =m=change in rent/change in square foot
For a unit increase in square feet rent increases by 0.4932
Interpretation of y intercept:
when square feet=0 rent is 992.99
Solutiond:
when squarefeet=800
Rent=0.4932(squarefeet)+992.99
=Rent=0.4932(800)+992.99
=1387.55
