Answer:
The conditions for carrying out a significance test are:
1. It must be a Random sampling
2. It should be a Normal distribution
3. It should be Independent
Step-by-step explanation:
SRS means simple random sample; it is a sampling technique in which individuals can be chosen from the population in such a way that every individual stands an equal chance to be selected as the sample.
The conditions needed or required to carry out a significance test of the teacher's suspicion are:
1. It must be a Random sampling
2. It should be a Normal distribution
3. It should be Independent
All of these conditions are met; the sampling is random as indicated by SRS, it is a normal distribution because one popular rule states that a sample size of at least 30 is enough and here we have a sample size of 45, it is independent because the sample size of 45 is less than 10% of the population
C) 3/9 because there are a total of nine coins and there are three quarters meaning there is a bout a 1 in 3 chance you’ll pull a quarter out
is ≈3.32 and ≈ 6.71. Look at the whole numbers, or integers, between 3 and 6. You will have 4 and 5. SInce we are looking for the sum of the integers, your sum will be 9. Hope this helped.
Answer:
Step-by-step explanation:
in a square pyramid the base area plus the area of the triangular faces is equal to the total area so we take (9*5) *1/2=22.5 then we multiply 22.5 *4= 90 so we take 90 + 5*5 = 115 so the total area is 115
V=1/3Ah. If V = 16 when A = 24, h is equal to 2
