A newspaper report claims that 30% of all tea-drinkers prefer green tea to black tea. Leo is the office manager at a company with thousands of employees. He wonders if the newspaper’s claim holds true at his company. To find out, Leo asks a simple random sample of 125 tea-drinking employees which they prefer: green tea or black tea.
Here's Leo's null hypothesis:The proportion of all tea-drinkers at the company that prefer green tea to black tea is...

He wants to see if the proportion of the 125 tea-drinking employes is, as the newspaper report claims, 30%.

Then the null hypothesis says that this is false and that there is no relation between the events.

Then the null hypothesis is:

The proportion of all tea-drinkers at the company that prefer green tea to black the is not the 30%

Which is the negation of the thing that Leo wants to check.

answer: on graphs, the open and closed circles, or vertical asymptotes drawn as dashed lines us identify discontinuities.

as before, graphs and tables allow us to estimate at best.

when working with formulas, getting zero in the denominator indicates a point of discontinuity.

when working with piecewise-defined functions, check for discontinuities at the transition points where one piece ends and the next begins.
