Answer: See the screenshot below.
Explanation:
We'll be using these trig functions
The inverse of those help us find the angle. Notation like arcsine is the same as inverse sine denoted as on many calculators.
The decimal results are approximate.
Answer:
Doubtful.
Step-by-step explanation:
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
