Excel was asked to generate 50 poisson random numbers with mean λ = 5. x frequency 0 1 1 1 2 4 3 7 4 7 5 8 6 10 7 3 8 3 9 4 10 1 11 1 click here for the excel data file (a) calculate the sample mean. (round your sample mean value to 2 decimal places.) sample mean (b) carry out the chi-square test at α = .05, combining end categories as needed to ensure that all expected frequencies are at least five. (round your test statistic value to 3 decimal places and the p-value to 4 decimal places.) test statistic d. f. p-value (c) the observations were coming from a poisson distribution. true false

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.

where did you get them? if you picked from the grass, is is probably poisonous.
