N= 7.01 :D I’m pretty sure that’s the answer :)
Answer: The sample size would be needed = 385
Step-by-step explanation:
Let p be the prior population proportion.
Margin of error = E
When not estimate of p is given , the formula to calculate the minimum sample size <em>n</em> =
, where z* = critical value for given confidence interval.
Here z* for 95% confidence level is 1.96.
E=5%=0.05
Then 
Hence, the sample size would be needed = 385
Answer:the length 7
Step-by-step explanation:each one is times 3 6x3 8x3 3x7=21
I'm pretty sure the answer is 5 because I did 50% of 50 which is 5
