<u>Confidence Interval</u>
When the population standard deviation is known, the formula for a confidence interval for a population mean
is:
Where n is the sample size and z is the corresponding z-value from the standard normal distribution for the selected confidence level. The value of z for a 95% confidence interval is z=1.96. The rest of the values are
Calculating the confidence interval
Or, equivalently
<h3>Answer: Choice C) 
</h3>
This is a more complicated way to write
The range is the set of all possible y outputs of a function. So we use the graph to see what y values are possible. The graph shows that y can be anything smaller than y = 2. We can't actually reach y = 2 itself due to a horizontal asymptote here.
In interval notation, the answer would be with the curved parenthesis to indicate "do not include y = 2 as part of the range".
