Using the t-distribution, as we have the standard deviation for the sample, it is found that the 95% confidence interval for the number of units students in their college are enrolled in is (11.7, 12.7).
<h3>What is a t-distribution confidence interval?</h3>
The confidence interval is:

In which:
is the sample mean.
- s is the standard deviation for the sample.
The critical value, using a t-distribution calculator, for a two-tailed <em>95% confidence interval</em>, with 49 - 1 = <em>48 df</em>, is t = 2.0106.
Hence:


The 95% confidence interval for the number of units students in their college are enrolled in is (11.7, 12.7).

The graph suggestion about green tea is that Green tea is inelastic in terms of supply and The supply of green tea does not change sharply with the price.
- In economics, when a commodity is inelastic, The supply or demand is not that moved (sharply or sensitive) to changes in the price of that commodity (price of green tea)
Conclusively, we can therefore say that the graph suggestion about green tea is that Green tea is inelastic in terms of supply and The supply of green tea does not change sharply with the price.
