Carry out a simulation experiment using a statistical computer package or other software to study the sampling distribution of x when the population distribution is lognormal with e[ln(x)] ¼ 3 and v[ln(x)] ¼ 1. consider the four sample sizes n ¼ 10, 20, 30, and 50, and in each case use 500 replications. for which of these sample sizes does the x sampling distribution appear to be approximately normal?

yes

step-by-step explanation:

the correct answer is b. negative exponential growth.

step-by-step explanation:

you can tell it's an exponential function because it decreases rapidly then levels out and never touches the x-axis.

it is negative because the y-axis decreases as the x-axis increases.

therefore it is a negative exponential growth graph.

the number of possible outcomes that do not show a 1 on the first spinner and show the number 4 on the second spinner is 2.

spinner 1 spinner 2

1                     1

1                     2

1                     3

1                     4

2                   1

2                   2

2                   3

2                   4   = not 1, and 4

3                   1

3                   2

3                   3

3                   4 = not 1, and 4

only 2 outcomes have passed the given condition.
