Using the z-distribution, it is found that:
- The 95% confidence interval is of -1.38 to 1.38.
- The value of the sample mean difference is of 1.74, which falls outside the 95% confidence interval.
<h3>What is the z-distribution confidence interval?</h3>
The confidence interval is:

In which:
is the difference between the population means.
In this problem, we have a 95% confidence level, hence
, z is the value of Z that has a p-value of
, so the critical value is z = 1.96.
The estimate and the standard error are given by:

Hence the bounds of the interval are given by:


1.74 is outside the interval, hence:
- The 95% confidence interval is of -1.38 to 1.38.
- The value of the sample mean difference is of 1.74, which falls outside the 95% confidence interval.

Answer:
3 3/10
Step-by-step explanation:
Step 1: Convert 2 4/5 to improper
2 4/5 = 14/5
Step 2: Rewrite
14/5 + 1/2
Step 3: Find common denominator
14/5(2/2) + 1/2(5/5)
28/10 + 5/10
Step 4: Add
33/10
Step 5: Simplify
