Determine whether the following graph can represent a variable with a normal distribution explain your reasoning. if the graph appears to represent a normal distribution, estimate the mean and standard deviation.
could the graph represent a variable with a normal distnbution? explain your reasoning select the correct choice below and, if necessary, fill in the answer boxes within your choice.
o a no, because the graph is skewed left
ob. no, because the graph is skewed right
o c. yes, the graph fulfills the properties of the normal distribution the mean is approximately and the standard deviation is about
(type whole numbers.)
od. no, because the graph crosses the x-axis.

First, think of what you know. you know that the number t the end of the equation will need to be subtracted because it is the money he lost from buying the lawn mower. and your first two weeks have negative profit, so that tells you that c and d are wrong. now you can plug any of the weeks into a and b to see which one works. i'll start with plugging week 1 into a.this isn't right because it says your answer for week one should be -90.so now we need to try the same thing with b.this one got you the right answer, (sometimes if you only check with one of the weeks multiple will work so you need to check with more of the weeks, but it worked out fine here)this means that b is the correct answer.let me know if you need more clarification. i hope this : )
