Answer:
b. Ha: # of bugs with the new pesticide = # of bugs with the old pesticide
Explanation:
As seen in the question above, the new insecticide may have better results than the old insecticide that David used in his garden. To find out if this is true, David decides to spray one side of the Garden with the new insecticide and spray the other side of the garden with the old insecticide, so that he can count which of the two insecticides killed more insects and thus determine which of the products is more efficient.
To determine efficiency, David's chances are:
- # of bugs with the new pesticide < # of bugs with the old pesticide
- # of bugs with the new pesticide > # of bugs with the old pesticide
However, it is necessary to consider an alternative hypothesis, where the evaluation of the results is null. Thus, the alternative hypothesis for David's experiment is:
- # of bugs with the new pesticide = # of bugs with the old pesticide
Answer:
Historians who study world wars have a battle of their own. It’s a debate over how influential industrialization and capitalism were as both a cause and effect of the wars.

Despite few being worried about their drinking, social media advertisements targeted for young adults with sleeping problems reached many who also drank heavily. Additionally, advertisements that promote sleep were more successful than those that promoted drinking. Cost-effectiveness was moderate for engagement (impressions to clicks), great for conversion (clicks to survey completion), and fair for enrollment when compared to earlier trials. These statistics show how effective sleep-related social media advertising is at reaching young adults who abuse alcohol and asking them for help.
<h3>
Describe Sleep intervention?</h3>
There were six different kinds of sleep interventions identified, including yoga, mindfulness, weight reduction programs, cognitive behavioral therapy for insomnia (CBT-I), sleep hygiene education, and adjusting the color temperature of fluorescent lights in the workplace. Only CBT-I improved presenteeism and sleep problems as compared to a control group. The results of this study also demonstrate that presenteeism is evaluated in a heterogeneous manner.
