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
The other number is -3.
Step-by-step explanation:
Step 1; First we develop formulae for the given information. A number is added with 3 and the resulting sum is multiplied by 4. This number is then divided by 2 and the quotient is 0. Assume the unknown number is x, then the given information is as follows
The quotient of is 0. So
= 0.
Step 2; Now we solve the above equation. The denominator is taken to the RHS and the RHS remains zero.
= 0, 4(x+3)= 0, 4x+ 12 = 0, 4x = -12, x =
= -3.
So the other number is -3.
