Before hypothesis testing and at the beginning of a study, a researcher is advised to conduct _____ because it _____.
ZanzabumX [31]

Answer:

d. a power analysis; tells the researcher the number of participants needed for trustworthy results.

Step-by-step explanation:

A control experiment can be defined as an experiment in which a condition assumed to be a probable cause of the effect is being compared to the same situation by the scientist without involving or using the suspected condition.

A hypothesis is considered to be tentative or an educated guess and can be defined as a testable explanation for an observation or a scientific problem. An example of a hypothesis is saying, Corona virus is caused by the introduction of the "5G" technology.

This ultimately implies that, for any hypothesis to be acceptable in science, it must be supported by observations and the results of control experiments; this give rise to factual informations, theories and by extension solutions to problems.

Before hypothesis testing and at the beginning of a study, a researcher is advised to conduct a power analysis because it tells the researcher the number of participants needed for trustworthy results.

A power analysis should always be conducted before the collection of data because it will help you as a researcher to determine the smallest sample size that's accurate enough to detect the effect of a specific test at the desired statistical significance level.

Can someone help me solve this and explain it to me? <br> −1/6(x−18)+1/3(x+3)=x+4
KATRIN_1 [288]

Answer:

Below.

Step-by-step explanation:

So calculate.

-1/6x+3+1/3x+1=x+4.

Cancel equal terms.

-1/6x+4+1/3x=x+4

Multiply both sides -1/6x+1/3x=x

collect like terms.

-x+2x=6x

move the variable from right to left.

x=6x

collect like terms

x-6x=0

Divide both sides

-5x=0

x=0

PLEASE IM GONNA DIE Paloma rides a scooter. She travels 10 ft. For every 1 second.
Nesterboy [21]

Answer:

She is incorrect; Paloma's ratio of seconds travelled to feet travelled is 1:10.

Step-by-step explanation:

Her ratio is 1:10 because the first number is the number of seconds, and the second number is the number of feet. So for every 1 second, she travels 10 feet, as indicated in the original problem.

Hope this helps.
