Step-by-step explanation:

An experimental research is one where the investigator study the effects from random samples he got and tested. the investigator manipulates parameters to considers some underlying factors in order to arrive at a conclusion. it is usually used to investigate relationships between variable and make comparison. In this case the investigator is conducting a research on how the consumption of oatmeal in adults reduces the level of bad cholesterol, he measures and study the level of bad cholesterol for 6months and then compare their results.

for example, I can conduct an extensive experimental study on the long term effects of exhaust fumes on the passengers (particularly adults between the ages of 25-50) of public transport in Nigeria. this will be studied and their effects will be compared and a conclusion will be reached on the exposure and the non exposure as the case maybe. most underlying conditions of experimental study are under the direct control of the researcher of the investigator. there are three different types of experimental research ; Pre-experimental study, quasi-experimental study and true-experimental study.

20) Which of the following is in ascending order?

Lelechka [254]

<h3>Answer:- </h3>

$\longrightarrow \sf h) \:\:\dfrac{2}{3},0.67,70\%,0.8$

<h3>Solution:-</h3>

Let us first write all the provided number in decimal

$\quad\leadsto\sf \dfrac{2}{3}= 0.\bar{66}$

$\quad\leadsto\sf 70 \% = \dfrac{70}{100}$

$\quad\quad\quad\implies\sf 0.7$

$\quad\leadsto 0.67$

$\quad\leadsto 0.8$

Comparing all the numbers now -

$\longrightarrow \sf 0.\bar{66}$

$\longrightarrow\sf \dfrac{2}{3}$
