A sample with size has , and . The dotplot for this sample is given below. A dotplot ranging from 58 to 95 with dots plotted as follows: 1 dot above 58, 1 dot above 68, 1 dot above 77, 1 dot above 81, 2 dots above 86, 1 dot above 90, 2 dots above 93, 5 dots above 94, and 4 dots above 95. Indicate whether or not it is appropriate to use the t-distribution. Choose the answer from the menu; Indicate whether or not it is appropriate to use the t-distribution. If it is appropriate, give the degrees of freedom for the t-distribution and give the estimated standard error. If it is not appropriate, enter in both of the answer fields below. Enter the exact answer for the degrees of freedom and round your answer for the standard error to two decimal places.

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.
