A population of rabbits has a mean life span of 10 years with a standard deviation of 2.6 days. If a sample of 30 rabbits is taken from this population, what is the probability the sample will have a sample mean life span of less than 9 years rounded to the nearest tenth of a percent? (Do not type in the percent symbol)

d

step-by-step explanation:

by observation, we can see that the the graph is simply the graph of y = |x| that has been shifted 4 units downwards and 3 units to the left.

we can recognize in choice d :

y = | x + 3 |   - 4 (rewriting in general form)

y = | x - (- 3) |   - 4

the "-4 " term means   that the graph has been shifted by 4 units in the negative y direction

the "-3 " term means   that the graph has been shifted by 3 units in the negative x direction

this matches our observation of the graph described above.
