Our values are,
Jelly Bean Mix.
The sample for us is n=200
And our proportion (x) is 40 .
We can calculate with this dates the sample proportion and make he test statistic.
We use the formula for Test statistic, that is given by,
We see that our P-value: 0.048 (From the Table)
We note that p-value is less than 0.05, so we should to rejecyt the null hypothesis and conclude that the calim is doubtful
