Answer:
Time = 133.3 secs
Step-by-step explanation:
<u><em>Speed = Distance / Time</em></u>
<em>Rearranging the formula</em>
Time = Distance / Speed
Where D = 200 m , S = 1.5 m/s
Time = 200 / 1.5
Time = 133.3 secs
Answer:
6 inches of tape
Step-by-step explanation:
To find the total amount of tape that Marge used, you can take the measure of each piece (
) and multiply by the total number of pieces cut (16):
So, Marge used 6 inches of tape altogether.
Answer:
The major condition that needs to be satisfied before a t-test is performed that the question satisfies easily is the use of random sampling to obtain sample data.
Step-by-step explanation:
The major conditions necessary to conduct a t-test about a mean include;
- The sample extracted from the population must be extracted using random sampling. That is, the sample must be a random sample of the population.
- The sampling distribution must be normal or approximately normal. This is achievable when the population distribution is normal or approximately normal.
- Each observation in the sample data must have an independent outcome. That is, the outcome/result of each sub-data mustn't depend on one another.
Of the three conditions that need to be satisfied before the conduction of a t-test, the first condition about using a random sampling technique is evidently satisfied.
It is stated in the question that 'A private investigator hired by a competitor takes a random sample of 47 games and tries to determine if there are more than 7 glitches per game'.
