4^3/2 or 5^3/2
Anything with 3/2 in the exponent
Answer:
z ≈ 145.62
Step-by-step explanation:
using the sine ratio in the right triangle
sin18° = 
= 
( multiply both sides by z )
z × sin18° = 45 ( divide both sides by sin18° )
z = 
≈ 145.62 ( to the nearest hundredth )
From the sample used to find out what psychology majors would join the club and if it is biased, we can say that;
<u><em>- Yes, the sampling method is biased. </em></u>
<u><em>- The likely direction of the bias is because you only asked 5 people which </em></u>
<u><em>is not a significant percentage of those offering psychology majors and as </em></u>
<u><em>such the 4 out of 5 gotten is likely going to be an over estimation of those </em></u>
<u><em>who are willing to pay to join this club.</em></u>
We are told that;
- You want to start a club.
- This club is for psychology majors.
- You want to find the proportion of those in the psychology majors that will join this club you want to organize.
- Now, out of all the students offering psychology majors, you only asked 5 of them if they will be interested. Since 4 out of the 5 are interested and you want to use that to form a basis of the proportion of those interested , it would lead to <em>sampling bias</em> since the population is not adequately represented.
Therefore, this would lead to sampling bias and thus the sample is biased.
