Bart) IV: time in microwave
DV: mice strength
Conclusion: the time in the microwave does not affect the mices strength
Improvement: Retest
Lisa) IV: Ragooti hair cream
DV: hair growth
Hypothesis: If rogooti is used in hair then it will increase growth speed because it contains special ingredients
Make sure it is outdoors, roof mounted, or in the attic.
Most roof antennas will give you radio reception similar to a car radio, or often better.
Try repurposing a TV antenna you already have; use an FM splitter to use it on your radio. ...
Consider an omnidirectional radio antenna.
C. It’s the only choice that limits a right. Think about it, the rest are granting rights.
Answer:
- <u><em>D. No, because $100,000 is much greater than the values used in the experiment.</em></u>
<u><em></em></u>
Explanation:
<em>Correlations</em>, when have strong correlation coefficients, which r = 0.9 is, may be good predictors within the limits of the range of the data.
Trying to extrapolate the <em>linear relationship</em> between the variables, <em>x = advertising spending and y= product sales</em>, way beyond the limits of the data used for the study, is too risky, because the data may be linear just for some stages (ranges) but behave very different in other ranges.
As, the option D. states, <em>$100,000 is much greater that the values used in the experiment</em>; hence, the correlation would likely would not be a good predictor for that input.
