Astudy was done that monitored the amount of words spoken by men and women per day. based on their research, they were able to predict that the average number of words spoken by all men is between 24000 and 25000 words per day. what part of the field of statistics is this?

Inference

Step-by-step explanation:

Inference is the way toward reaching determinations about a parameter one is looking to quantify or assess. Frequently researchers have numerous estimations of an article say, the mass of an electron and wish to pick the best measure. One chief methodology of measurable deduction is Bayesian estimation, which fuses sensible desires or earlier decisions just as new perceptions or exploratory outcomes.

step-by-step explanation:

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.
