Answer: c. 0.0778
Step-by-step explanation:
Let X is the number of non-authentic names in her sample with parameter :
n= 5 and p=40% = 0.40
Binomial probability distribution, the probability of getting success in x trials :-
![P(X=x)=^nC_xp^x(1-p)^{n-x}](https://tex.z-dn.net/?f=P%28X%3Dx%29%3D%5EnC_xp%5Ex%281-p%29%5E%7Bn-x%7D)
We have ,
![P(X=0)=^{5}C_0(0.40)^0(1-0.40)^{5}\\\\=(1)(0.60)^{5}\\\\=0.07776\approx0.0778](https://tex.z-dn.net/?f=P%28X%3D0%29%3D%5E%7B5%7DC_0%280.40%29%5E0%281-0.40%29%5E%7B5%7D%5C%5C%5C%5C%3D%281%29%280.60%29%5E%7B5%7D%5C%5C%5C%5C%3D0.07776%5Capprox0.0778)
Thus , the correct answer is option c. 0.0778

Step-by-step explanation:
Below are the null and alternative Hypothesis,
Null Hypothesis, H0: μ = 35000
Alternative Hypothesis, Ha: μ < 35000
Test statistic,
z = (xbar - mu)/(sigma/sqrt(n))
z = (33450 - 35000)/(5978/sqrt(50))
z = -1.83
P-value Approach
P-value = 0.0336
As P-value >= 0.02, fail to reject null hypothesis.
There is not sufficient evidence to conclude that the average College tuition for a law degree costs at least thirty five thousand dollars.
