Answer:
At least 1537 samples needed to estimate the true average number of eggs a queen bee lays with 95 percent confidence
Step-by-step explanation:
Minimum sample size required can be found using the formula
N≥
where
- z is the corresponding z-score of 95% confidence level (1.96)
- s is the standard deviation (10)
- ME is the margin of error (0.5)
then N≥
=1536.64
Then, at least 1537 samples needed to estimate the true average number of eggs a queen bee lays with 95 percent confidence
