Suppose you want to test the claim that the true mean number of children a woman thinks a family should have is less than 3. You take a random sample of 30 women and find a sample mean of 2.5 children and a sample standard deviation of 1.2 children. The corre- sponding test statistic is – 2.28. Which of the following is the correct p-value to test this claim? (a) p-value = 0.0113 (b) p-value = 0.0226 (c) p-value = 0.9887 (d) 0.01 < p-value < 0.02 (e) 0.02 < p-value < 0.04

two data sets with the same median will not have the same varaibility

step-by-step explanation:

8+10

step-by-step explanation:

you multiply 4 by 2 and 5 by 2

if i put something wrong your not gonna like it so rather not say nothing.

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.
