Answer: n= 14
Step-by-step explanation:
The formula to find the sample size :_

, where p= Prior estimate of population proportion.
z* = Critical value.
E= Margin of error.
Given : Prior estimate of population proportion : p= 0.025
We know that , the critical value for 90% confidence interval :

E= 7.0%=0.070
Then , the required minimum sample size :

i.e. n= 14
Hence, the sample size needed : n= 14
Answer:
If it's 0.06 it's 3/50.but if it's 0.6 it's 3/5
Answer:
Top Image: 56°
Bottom Image: 134°
Step-by-step explanation:
I'm not sure which image you have a question on, so I'll just solve both.
Top Image:
We know that the sum of the angles will add up to 180 and that the angles of the triangle are f, f, and 68°. Therefore, we can set up the following equation:
f + f + 68° = 180°
Solving this gets f = 56°
Bottom Image:
We know that the sum of the angles will add up to 180 and that the angles of the triangle are 23°, 23°, and g. Therefore, we can set up the following equation:
23° + 23° + g = 180°
Solving this gets g = 134°
