First, you have to get the equation to the normal form of a line. To do this, you divide both sides by -6 to get

. The y-intercept is at -4 and your slope is 2/3. Use this to graph the equation.

Hypothesis testing

For this problem, we need to use the t-student distribution to make inference about the data. We calculate the t-statistics as below:

Using a t-statistics table, or using the function TDIST in Microsoft Excel with
with two-tailed distribution, we obtain
.
Lets say there were 100 people and 40 ate sandwiches on the first day then 25 percent of 40 is 10, so 10 had sandwiches two days in a row i would say it is true
