Answer: D. The dotplot is closer to approximately normal than the distribution of the population with mean $150 and standard deviation $10.
Step-by-step explanation:
Based on the dotplot created from the 100 sample, the dotplot is closer to approximately normal than the distribution of the population with mean $150 and standard deviation $10.
The mean of the sampling distribution is just exactly like the population mean. On the other hand, the standard deviation will be: = 50/✓25 = 50/5 = 10
Therefore, the correct option is D.
Answer:
9 dollars per dog
Step-by-step explanation:
45/5=9
you divide to find the unit rate per 1 dog walked.
It is .6 because 6 doesn't repeat and by the 10 you go left one
Your vertex would be (-1,-5)
and your axis of symmetry is x=-1
Red has a greater value.
Blue = -2
Red = 3
