Question

A researcher has a set of numbers whose mean is equal to 4.9. The researcher wants

to know if that set of numbers likely comes from the uniform distribution on the

interval of 1 to 10 using the equation method.

a. Determine the theoretical expected value for the uniform distribution on the

interval of 1 to 10.

b. With reference to the lecture slides, create the distribution of means from 99

random simulated draws from the uniform distribution on the interval from

1 to 10.

c. Plot the histogram (function hist()) of the simulated distribution of means

and place a vertical line on that plot at the location of the researcher's mean

(abline(v=4.9)) and another line showing the theoretically expected value.

D Determine the probability that the researcher's mean comes

distribution (the monte-carlo p-value).

e. Explain your conclusion.
