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>
Maria(1 person) and 3 friends
Total of 4 friends.

1/5 times 400 equals 80. It's true only 80 students voted yes. 4/5 times 400 equals 320 students voted guess.
Answer:
<h2><u><em>
a = 13/4</em></u></h2>
Step-by-step explanation:
√(5²+12²) = ∛(64a³)
√(25+144)=√(64a)
√169 = √(64a)
13 = 4a
a = 13/4
1 has the greatest value because it is a whole number
