Adam thinks the five people who sit next to him in class spend the same amount of money on their haircut on average. To find out he keeps track of how much their haircuts cost for the next couple of months. Assuming the cost of a haircut is random, normal, and the variances are the same, test if the average cost is equal (the tip is included in the price). Name Number of haircuts Average Cost Standard deviation for one haircut
Mallory 7 16.7 6.5
Matt 20 15.2 8
Stacey 18 16.1 5
Whitney 15 20.8 5.3
James 23 20.2 6

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.
