Answer:
Lets take the hypothesis
<em>zα/2 </em>
<em>- zα/2 </em>
Step-by-step explanation:
<em>α/2 = 0.10/2 = 0.05
</em>
<em>z(0.05) = 3.92
</em>
<em>-z(0.05) = -3.92
</em>
No it does not affect the sum because they have the same sign so it wouldn't make a difference
It's 3/10 since we did it 10 times and it landed tails 3 times
