3. section 8.1 distribution of the sample mean explain it:
a) explain what a sampling distribution is.
b) state the central limit theorem.
c) without doing any computation, decide which has a higher probability, assuming each sample is from a population that is normally distributed with: μ

i think it would be 42cm

8

step-by-step explanation:

just put √(2) * √(32) into a calculator. that will make the answer be 8.

answer:

total cost for tiles and paints is $924.  

step-by-step explanation:

we have been given that a community hall is in the shape of a cuboid. the hall is 40m long 15m high and 3m wide.

the paint will be required for 4 walls and ceiling.

let us find area of walls and ceiling.

therefore, the area of walls and ceiling is 1410 square meters.

given: cost for 10 litre of paint is $10 and 10 litre paint covers 25 square meter. therefore,

therefore, the total painting cost is $564.

tiles will be required for floor. let us find the area of floor.

given: 1m squared floor tiles costs $3. so,

therefore, the total tiles cost is $360.

now let us find combined total cost of tiles and paint.

therefore, the combined total cost of tiles and paint is $924.
