The true average diameter of ball bearings of a certain type is supposed to be .5 in. A one-sample
t-test will be carried out to see whether this is the case. What conclusion is appropriate in each of
the following situations?
a. n = 13, t = 1.6, α = 0.05
b. n = 13, t = -1.6, α = 0.05
c. n = 25, t = -2.6, α = 0.01
d. n = 25, t = -3.9

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.
