Natalija [7]

Answer:

The correct answer is "664".

Step-by-step explanation:

The given values are:

Margin of error,

E = 5%

i.e.,

   = 0.05

Level of confidence,

C = 99%

i.e.,

   = 0.99

Level of significance,

α = 0.01

From the z value table,

Critical z = 2.576

As we know,

The required sample size n will be:

=  (\frac{z}{E} )^2\times p(1-p)

On substituting the values, we get

=  (\frac{2.576}{0.05} )^2\times 0.5(1-0.5)

=  (51.52)^2\times 0.25

=  2,654.31\times 0.25

=  663.5776

i.e.,

=  664

what is the height of each student in my class?

what is the highest temperature of each month this year?

Step-by-step explanation:

A statistical question is one that can be answered by collecting data and where there will be variability in that data

one key word is “each” because you know there will be a variety of responses

options where you have to count something and find a total wouldn’t be statistical because you’re finding only one number and that’s not a variety
