A candy company claims that its jelly bean mix contains 15% blue jelly beans. Suppose that the candies are packaged at random in
I am Lyosha [343]

Answer:

Doubtful.

Step-by-step explanation:

Our values are,

P=0.15 \rightarrow 15\%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.

p=\frac{x}{n} = \frac{40}{200} = 0.20

H_0:P=0.15

H_1:P \neq 0.15

We use the formula for Test statistic, that is given by,

z= \frac{p-P}{\sqrt{\frac{P-(1-P)}{n}}}

z= \frac{0.20-0.15}{\sqrt{\frac{0.15(1-0.15)}{200}}}

z= 1.98

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
