Answer: have each experimenter test randomized blocks of conditions.
Step-by-step explanation:
Randomized block design is a technique used in controlling nuisance in an experiment due to excessive variables, experimental conditions, etc which can make the experiment complex/ complicated.
Answer:
n = -3 or 8
Step-by-step explanation:
2n² = 10n +48 (rearrange)
2n²- 10n - 48 = 0 (divide all terms by 2)
n²- 5n - 24 = 0
by factorization,
(n+3)(n-8) = 0
hence,
n+3 = 0 ----> n = -3
or
n-8 = 0 ----> n = 8
Answer: Option 'A' is correct.
Step-by-step explanation:
Since we have given that
the sample is chosen by asking people on the street.
Since every member chosen from the sample has an equal chance.
so, it is considered as simple random.
Systematic random is the method in which every n th member is selected or chosen.
Stratified random is the method of sampling in which population is divided into groups and the sample is making by choosing every member from each group
Cluster is the method of sampling in which the population is divided into groups and the sample is making by choosing every member from some of the group instead of every group.
But here, we have chosen by asking people on the street.
So, every member has equal chances.
So, it is sample random.
Hence, Option 'A' is correct.
