The sample of sizes 2 and their mean are given below.
Step-by-step explanation:
The population consist of 5 values, S = {1, 3, 4, 4, 6}.
The number of samples of size 2 (without replacement) that can be formed from these 5 values is:
Th formula to compute the mean is:
List the 10 samples and their mean as follows:

Answer:
We are 90% confident that the true proportion of teenagers who have used at least one informal element in school writing assignments is between 0.464 and 0.518
Step-by-step explanation:
We can begin finding the estimator for the proportion of interest:
The confidence level is 90% , and the significance level would be given by and . And the critical value would be given by:
The confidence interval for the mean is given by the following formula:
Replacing the info given we got:
We are 90% confident that the true proportion of teenagers who have used at least one informal element in school writing assignments is between 0.464 and 0.518
