Go to an online normal random variable generator; and generate 20 normally distributed random numbers. state these numbers that you generated. construct a 95% confidence interval for the mean of these numbers. does your confidence interval contain the initially assigned mean?

(-0.507,0.406)

Step-by-step explanation:

The online normal variable generator gave the following data set with n = 20

-0.42,-0.74,-1.54,1.16,1.19,0.32,-0.63,0.95,-1.8,1.49,0.02,0.7,0.56,-1.28,0.16,-0.05,0.28,-0.82,1.25,-1.81

For a normally distributed data,

Mean = 0 and Standard deviation = 1

Formula:

where are data points, is the mean and n is the number of observations.

Mean =

Standard Deviation, =

Confidence interval =

At 95%,

Putting all the values, we get the confidence interval as:

it is a. 4.2 because 7.6-3.4 gets the remaining length of 4.2. i might be wrong but i am pretty sure this is the answer.
