Answer:

Option C.

Step-by-step explanation:

It is given that,

Total number of applicants = 9

Number of job = 3

We need to select 3 applicants out of 9. So, the required number of ways is

^9P_3=\dfrac{9!}{(9-3)!}

^9P_3=\dfrac{9\times 8\times 7\times 6!}{6!}

^9P_3=9\times 8\times 7

^9P_3=504

Therefore, there are ^9P_3=504 ways the positions can be filled because the order in which the applicants are chosen matters.

Hence, the correct option is C.

You want to create a 99% confidence interval with a margin of error of .5. Assuming the population standard deviation is equal t
miss Akunina [59]

Answer:

Sample size minimum is 60

Step-by-step explanation:

given that you want to create a 99% confidence interval with a margin of error of .5.

The population  standard deviation is equal to 1.5

i.e. \sigma = 0.5

Confidence level = 99%

Since population std deviation is known, we can use Z critical value for finding margin of error

Z critical value for 99% = 2.58

Margin of error = 2.58*\frac{1.5}{\sqrt{n} }

Equate this to 0.5 and solve for n

2.58*\frac{1.5}{\sqrt{n} }=0.5\\\sqrt{n} =7.74\\n =59.90\\n=60
